               INFORMATION REQUIRED IN THE REGISTRATION STATEMENT

Item 3.   Incorporation of Documents by Reference.
          --------------------------------------- 

     There are hereby incorporated by reference in this Registration Statement
the following documents and information heretofore filed with the Securities and
Exchange Commission:

     (a)  The Company's latest Annual Report on Form 10-K for the year ended
August 28, 1997, filed pursuant to Section 13(a) of the Securities Exchange Act
of 1934, as amended (the "1934 Act") (File No. 1-10658).

     (b)  The Company's latest Quarterly Report on Form 10-Q for the quarter
ended February 26, 1998, filed pursuant to Section 13(a) of the 1934 Act (File
No. 1-10658).

     (c)  The description of the Company's Common Stock contained in the
Company's Registration Statement on Form 8-A, filed November 9, 1990 pursuant to
Section 12(b) of the 1934 Act (File No. 1-10658), including any amendment or
report filed with the Securities and Exchange Commission for the purpose of
updating such description.

     All reports and other documents filed by the Company pursuant to Sections
13(a), 13(c), 14 and 15(d) of the 1934 Act after the date of this Registration
Statement and prior to the filing of a post-effective amendment which indicates

Registration Statement and to be part hereof from the date of filing such
documents.

Item 4.   Description of Securities.
          ------------------------- 

     Not applicable.

Item 5.   Interests of Named Experts and Counsel.
          -------------------------------------- 

     Not applicable.

Item 6.   Indemnification of Directors and Officers.
          ----------------------------------------- 

     Section 145 of the Delaware General Corporation Law authorizes a court to
award, or a corporation's Board of Directors or stockholders to grant,
indemnification to directors and officers in terms sufficiently broad to permit
such indemnification under certain circumstances for liabilities (including
reimbursement for expenses incurred) arising under the Securities Act of 1933,
as amended (the "Securities Act") and for liabilities arising from other state
and federal causes of action. Section 11 of the Company's Certificate of
Incorporation and Article VII of the Company's Bylaws provide for the mandatory
indemnification of its officers, directors, 
<PAGE>
 
employees and agents to the extent permitted by Delaware General Corporation
Law. The Company has entered into agreements with its officers, directors and
certain key employees implementing such indemnification.

Item 7.   Exemption from Registration Claimed.

     Not applicable.

Item 9.   Undertakings.
          ------------ 

     (a)  The undersigned Registrant hereby undertakes:

     (1)  To file, during any period in which offers or sales are being made, a
post-effective amendment to this Registration Statement to include any
material information with respect to the plan of distribution not previously
disclosed in the Registration Statement or any material change to such
information in the Registration Statement.

     (2)  That, for the purpose of determining any liability under the
Securities Act each such post-effective amendment shall be deemed to be a new
<PAGE>
 
Registration Statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

     (3)  To remove from registration by means of a post-effective amendment any
of the securities being registered which remain unsold at the termination of the
offering.

     (b)  The undersigned Registrant hereby undertakes that, for the purpose of
determining any liability under the Securities Act, each filing of the
Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
1934 Act (and, where applicable, each filing of an employee benefit plan's
annual report pursuant to Section 15(d) of the 1934 Act) that is incorporated by
reference in the Registration Statement shall be deemed to be a new Registration
Statement relating to the securities offered therein, and the offering of such
securities at that time shall be deemed to be the initial bona fide offering
thereof.

     (c)  Insofar as indemnification for liabilities arising under the
Securities Act may be permitted to directors, officers and controlling persons
of the Registrant pursuant to the foregoing provisions, or otherwise, the
Registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the
Securities Act and is, therefore, unenforceable.  In the event that a claim for
indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a director, officer or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Securities
Act and will be governed by the final adjudication of such issue.

                                  SIGNATURES

     Pursuant to the requirements of the Securities Act of 1933, as amended, the
Registrant certifies that it has reasonable grounds to believe that it meets all
of the requirements for filing on Form S-8 and has duly caused this Registration
Statement to be signed on its behalf by the undersigned, thereunto duly
authorized, in the City of Boise, State of Idaho, on this 14th day of April,
1998.

     4.  Administration of the Plan.
         -------------------------- 

         (a)  Procedure.
              --------- 

              (i) Multiple Administrative Bodies. If permitted by Rule 16b-3,
                  ------------------------------    
the Plan may be administered by different bodies with respect to Directors,
Officers who are not Directors, and Employees who are neither Directors nor
Officers.

             (ii) Administration With Respect to Directors and Officers Subject
               ----------------------------------------------------------------
to Section 16(b). With respect to Option grants made to Employees who are also
- ----------------
Officers or Directors subject to Section 16(b) of the Exchange Act, the Plan
shall be administered by (A) the Board, if the Board may administer the Plan in
compliance with the rules governing a plan intended to qualify as a
discretionary plan under Rule 16b-3, or (B) a committee designated by the Board
to administer the Plan, which committee shall be constituted to comply with the
rules governing a plan intended to qualify as a discretionary plan under Rule
16b-3. Once appointed, such committee shall continue to serve in its designated
capacity until otherwise directed by the Board. From time to time the Board may
increase the size of the Committee and appoint additional members, remove
members (with or without cause) and substitute new members, fill vacancies
(however caused), and remove all members of the Committee and thereafter
directly administer the Plan, all to the extent permitted by the rules governing
a plan intended to qualify as a discretionary plan under Rule 16b-3.

             (iii) Administration With Respect to Other Persons. With respect to
                   --------------------------------------------  
Option grants made to Employees or Consultants who are neither Directors nor
Officers of the Company, the Plan shall be administered by (A) the Board or (B)
a committee designated by the 
<PAGE>
 
Board, which committee shall be constituted to satisfy Applicable Laws. Once
appointed, such Board may increase the size of the Committee and appoint
additional members, remove members (with or without cause) and substitute new
members, fill vacancies (however caused), and remove all members of the
Committee and thereafter directly administer the Plan, all to the extent
permitted by Applicable Laws.

         (b) Powers of the Administrator. Subject to the provisions of the Plan,
             ---------------------------
and in the case of a Committee, subject to the specific duties delegated by the
Board to such Committee, the Administrator shall have the authority, in its
discretion:

             (i) to determine the Fair Market Value of the Common Stock, in
accordance with Section 2(o) of the Plan;

             (ii) to select the Consultants and Employees to whom Options may be
granted hereunder;

             (iii)  to determine whether and to what extent Options are granted
hereunder;

             (iv) to determine the number of shares of Common Stock to be
covered by each Option granted hereunder;

             (v) to approve forms of agreement for use under the Plan;

             (vi) to determine the terms and conditions, not inconsistent with
the terms of the Plan, of any award granted hereunder. Such terms and conditions
include, but are not limited to, the exercise price, the time or times when
Options may be exercised (which may be based on performance criteria), any
vesting acceleration or waiver of forfeiture restrictions, and any restriction
or limitation regarding any Option or the shares of Common Stock relating
thereto, based in each case on such factors as the Administrator, in its sole
discretion, shall determine;

             (vii) to reduce the exercise price of any Option to the then
current Fair Market Value if the Fair Market Value of the Common Stock covered
by such Option shall have declined since the date the Option was granted;

             (viii) to construe and interpret the terms of the Plan and awards
granted pursuant to the Plan;

             (ix) to prescribe, amend, and rescind rules and regulations
relating to the Plan, including rules and regulations relating to sub-plans
established for the purpose of qualifying for preferred tax treatment under
foreign tax laws;
<PAGE>
 
             (x) to modify or amend each Option (subject to Section 14(c) of the
Plan), including the discretionary authority to extend the post-termination
exercisability period of Options longer than is otherwise provided for in the
Plan;

             (xi) to authorize any person to execute on behalf of the Company
any instrument required to effect the grant of an Option previously granted by
the Administrator;

             (xii)  to institute and Option Exchange Program; and

             (xiii) to make all other determinations deemed necessary or
advisable for administering the Plan.

         (c) Effect of Administrator's Decision.  The Administrator's decisions,
             ----------------------------------                                 
determinations, and interpretations shall be final and binding on all Optionees
and any other holders of Options.

     5.  Eligibility.  Nonstatutory Stock Options may be granted to Employees
         -----------                                                         
and Consultants.  Incentive Stock Options may be granted only to Employees.  If
otherwise eligible, an Employee or Consultant who has been granted an Option may
be granted additional Options.

     6.  Limitations.
         ----------- 

         (a) Each Option shall be designated in the Notice of Grant as either an
Incentive Stock Option or a Nonstatutory Stock Option.  However, notwithstanding
such designations, to the extent that the aggregate Fair Market Value:

             (i) of Shares subject to an Optionee's Incentive Stock Options
granted by the Company or any Parent or Subsidiary, which

             (ii) become exercisable for the first time during any calendar year
(under all plans of the Company or any Parent or Subsidiary) exceeds $100,000,
such excess Options shall be treated as Nonstatutory Stock Options. For purposes
of this Section 6(a), Incentive Stock Options shall be taken into account in the
order in which they were granted, and the Fair Market Value of the Shares shall
be determined as of the time of grant.

         (b) Neither the Plan nor any Option shall confer upon an Optionee any
right with respect to continuing the Optionee's employment or consulting
relationship with the Company, nor shall they interfere in any way with the
Optionee's right or the Company's right to terminate such employment or
consulting relationship at any time, with or without cause.

        (c) The following limitations shall apply to grants of Options to
Employees:

            (i) No employee shall be granted, in any fiscal year of the Company,
Options to purchase more than 500,000 Shares.
<PAGE>
 
            (ii) The foregoing limitations shall be adjusted proportionately in
connection with any change in the Company's capitalization as described in
Section 12.

            (iii) If an Option is canceled in the same fiscal year of the
Company in which it was granted (other than in connection with a transaction
described in Section 12), the canceled Option will be counted against the limit
set forth in Section 6(c)(i). For this purpose, if the exercise price of an
Option is reduced, the transaction will be treated as a cancellation of the
Option and the grant of a new Option.

     7.  Term of Plan.  Subject to Section 18 of the Plan, the Plan shall become
         ------------                                                           
effective upon the earlier to occur of its adoption by the Board or its approval
by the shareholders of the Company as described in Section 18 of the Plan.  It
shall continue in effect for a term of ten (10) years unless terminated earlier
under Section 14 of the Plan.

     8.  Term of Option.  The term of each Option shall be stated in the Notice
         --------------                                                        
of Grant; provided, however, that in the case of an Incentive Stock Option, the
term shall be ten (10) years from the date of grant or such shorter term as may
be provided in the Notice of Grant.  Moreover, in the case of an Incentive Stock
Option granted to an Optionee who, at the time Incentive Stock Option is
granted, owns stock representing more than ten percent (10%) of the voting power
of all classes of stock of the Company or any Parent or Subsidiary, the term of
the Incentive Stock Option shall be five (5) years from the date of grant or
such shorter term as may be provided in the Notice of Grant.

     9.  Option Exercise Price and Consideration.
         --------------------------------------- 

        (a) Exercise Price.  The per share exercise price for the Shares to be
            --------------                                                    
issued pursuant to exercise of an Option shall be determined by the
Administrator, subject to the following:

           (i) In the case of an Incentive Stock Option

               (A) granted to an Employee who, at the time the Incentive Stock
Option is granted, owns stock representing more than ten percent (10%) of the
voting power of all classes of stock of the Company or Parent or Subsidiary, the
per Share exercise price shall be no less than 110% of the Fair Market Value per
Share on the date of grant.

               (B) granted to any Employee other than an Employee described in
paragraph (A) immediately above, the per Share exercise price shall be no less
than 100% of the Fair Market Value per Share on the date of grant.

           (ii) In the case of a Nonstatutory Stock Option, the per Share
exercise price shall be determined by the Administrator.
<PAGE>
 
        (b) Waiting Period and Exercise Dates. At the time an Option is granted,
            ---------------------------------  
the Administrator shall fix the period within which the Option may be exercised
and shall determine any conditions which must be satisfied before the Option may
be exercised. In doing so, the Administrator may specify that an Option may not
be exercised until the completion of a service period.

        (c) Form of Consideration.  The Administrator shall determine the
            ---------------------                                        
acceptable form of consideration for exercising an Option, including the method
of payment.  In the case of an Incentive Stock Option, the Administrator shall
determine the acceptable form of consideration at the time of grant.  Such
consideration may consist entirely of:

            (i)  cash;

            (ii)  check;

            (iii)  promissory note;

            (iv) other Shares which (A) in the case of Shares acquired upon
exercise of an option, have been owned by the Optionee for more than six months
on the date of surrender, and (B) have a Fair Market Value on the date of
surrender equal to the aggregate exercise price of the Shares as to which said
Option shall be exercised;

            (v) delivery of a properly executed exercise notice together with
such other documentation as the Administrator and the broker, if applicable,
shall require to effect an exercise of the Option and delivery to the Company of
the sale or loan proceeds required to pay the exercise price;

            (vi) a reduction in the amount of any Company liability to the
Optionee, including any liability attributable to the Optionee's participation
in any Company-sponsored deferred compensation program or arrangement;

            (vii)  any combination of the foregoing methods of payment; or

            (viii) such other consideration and method of payment for the
issuance of Shares to the extent permitted by Applicable Laws.

     10.  Exercise of Option.
          ------------------ 

          (a) Procedure for Exercise; Rights as a Shareholder. Any Option
              -----------------------------------------------     
granted thereunder shall be exercisable according to the terms of the Plan and
at such times and under such conditions as determined by the Administrator and
set forth in the Option Agreement.

              An Option may not be exercised for a fraction of a Share.
<PAGE>
 
              An Option shall be deemed exercised when the Company receives: (i)
written notice of exercise (in accordance with the Option Agreement) from the
person entitled to exercise the Option, and (ii) full payment for the Shares
with respect to which the Option is exercised. Full payment may consist of any
consideration and method of payment authorized by the Administrator and
permitted by the Option Agreement and the Plan. Shares issued upon exercise of
an Option shall be issued in the name of the Optionee or, if requested by the
Optionee, in the name of the Optionee and his or her spouse. Until the stock
certificate evidencing such Shares is issued (as evidenced by the appropriate
entry on the books of the Company or of a duly authorized transfer agent of the
Company), no right to vote or receive dividends or any other rights as a
shareholder shall exist with respect to the Optioned Stock, notwithstanding the
exercise of the Option. The Company shall issue (or cause to be issued) such
stock certificate, either in book entry form or in certificate form, promptly
after the Option is exercised. No adjustment will be made for a dividend or
other right for which the record date is prior to the date the Shares are
issued, except as provided in Section 12 of the Plan.

              Exercising an Option in any manner shall decrease the number of
Shares thereafter available, both for purposes of the Plan and for sale under
the Option, by the number of Shares as to which the Option is exercised.

         (b) Termination of Employment or Consulting Relationship. Upon
             ---------------------------------------------------- 
termination of an Optionee's Continuous Status as an Employee or Consultant,
other than upon the Optionee's death or Disability, the Optionee may exercise
his or her Option, but only within such period of time as is specified in the
Notice of Grant, and only to the extent that the Optionee was entitled to
exercise it as the date of termination (but in no event later than the
expiration of the term of such Option as set forth in the Notice of Grant). In
the absence of a specified time in the Notice of Grant, the Option shall remain
exercisable for 30 days following the Optionee's termination of Continuous
Status as an Employee or Consultant. In the case of an Incentive Stock Option,
such period of time shall not exceed thirty (30) days from the date of
termination. If, at the date of termination, the Optionee is not entitled to
exercise his or her entire Option, the Shares covered by the unexercisable
portion of the Option shall revert to the Plan. If, after termination, the
Optionee does not exercise his or her Option within the time specified herein,
the Option shall terminate, and the Shares covered by such Option shall revert
to the Plan.

         (c) Disability of Optionee.  In the event that an Optionee's Continuous
             ----------------------                                             
Status as an Employee or Consultant terminates as a result of the Optionee's
Disability, the Optionee may exercise his or her Option at any time within
twelve (12) months from the date of such termination, but only to the extent
that the Optionee was entitled to exercise it at the date of such termination
(but in no event later than the expiration of the term of such Option as set
forth in the Notice of Grant).  If, at the date of termination, the Optionee
does not exercise his or her entire Option, the Shares covered by the
unexercisable portion of the Option shall revert to the Plan.  If, after
termination, the Optionee does not exercise his or her option within the time
specified herein, the Option shall terminate, and the Shares covered by such
Option shall revert to the Plan.
<PAGE>
 
         (d) Death of Optionee.  In the event of the death of an Optionee, the
             -----------------                                                
Option may be exercised at any time within twelve (12) months following the date
of death (but in no event later than the expiration of the term of such Option
as set forth in the Notice of Grant), by the Optionee's estate or by a person
who acquired the right to exercise the Option by bequest or inheritance, but
only to the extent that the Optionee was entitled to exercise the Option at the
date of death.  If, at any time of death, the Optionee was not entitled to
exercise his or her entire Option, the Shares covered by the unexercisable
portion of the Option shall immediately revert to the Plan.  If, after death,
the Optionee's estate or a person who acquired the right to exercise the Option
by bequest or inheritance does not exercise the Option within the time specified
herein, the Option shall terminate, and the Shares covered by such Option shall
revert to the Plan.

         (e) Rule 16b-3. Options granted to individuals subject to Section 16 of
             ----------     
the Exchange Act ("Insiders") must comply with the applicable provisions of Rule
16b-3 and shall contain such additional conditions or restrictions as may be
required thereunder to qualify for the maximum exemption from Section 16 of the
Exchange Act with respect to Plan transactions.

         (f) Suspension. Any Optionee who is also a participant in the
             ----------                       
Retirement at Micron ("RAM") Section 401(k) Plan and who requests and receives a
hardship distribution from the RAM Plan, is prohibited from making, and must
suspend, his or her employee elective contributions and employee contributions
including, without limitation on the foregoing, the exercise of any Option
granted from the date of receipt by that employee of the RAM hardship
distribution.

     11.  Non-Transferability of Options.  An Option may not be sold, pledged,
          ------------------------------                                      
assigned, hypothecated, transferred, or disposed of in any manner other than by
will or by laws of descent or distribution and may be exercised, during the
lifetime of the Optionee, only by the Optionee.

     12.  Adjustments Upon Changes in Capitalization, Dissolution, Merger, or
          -------------------------------------------------------------------
Asset Sale.
- ---------- 

          (a) Changes in Capitalization.  Subject to any required action by the
              -------------------------                                        
shareholders of the Company, the number of shares of Common Stock covered by
each outstanding Option, and the number of issued shares of Common Stock which
have been authorized for issuance under the Plan but as to which no Options have
yet been granted or which have been returned to the Plan upon cancellation or
expiration of an Option, as well as the price per share of Common Stock covered
by each such outstanding Option, shall be proportionately adjusted for any
increase or decrease in the number of issued shares of Common Stock resulting
from a stock split, reverse stock split, stock dividend, combination or
reclassification of the Common Stock or any other increase or decrease in the
number of shares of Common Stock effected without receipt of consideration by
the Company; provided, however, that conversion of any convertible securities of
the Company shall not be deemed to have been "effected without receipt of
consideration."  Such adjustment shall be made by the Board, whose determination
in that respect shall be final, binding, and conclusive.  Except as expressly
provided herein, no issuance by the Company of shares of stock of any class, or
securities convertible into shares of stock of any class, shall affect, and no
adjustment by reason thereof 
<PAGE>
 
shall be made with respect to, the number or price of shares of Common Stock
subject to an Option.

         (b) Dissolution or Liquidation. In the event of the proposed
             --------------------------   
dissolution or liquidation of the Company, to the extent that an Option has not
been previously exercised, it will terminate immediately prior to the
consummation of such proposed action. The Board may, in the exercise of its sole
discretion in such instances, declare that any Option shall terminate as of a
date fixed by the Board and give each Optionee the right to exercise his or her
Option as to all or any part of the Optioned stock, including Shares as to which
the Option would not otherwise be exercisable.

         (c) Merger or Asset Sale. In the event of a merger of the Company with
             --------------------
or into another corporation, or the sale of substantially all of the assets of
the Company, each outstanding Option may be assumed or an equivalent option or
right may be substituted by the successor corporation or a Parent or Subsidiary
of the successor corporation. The Administrator may, in lieu of such assumption
or substitution, provide for the Optionee to have the right to exercise the
Option as to all or a portion of the Optioned Stock, including Shares as to
which it would not otherwise be exercisable. If the Administrator makes an
Option exercisable in lieu of assumption or substitution in the event of a
merger or sale of assets, the Administrator shall notify the Optionee that the
Option shall be fully exercisable for a period of thirty (30) days from the date
of such notice, and the Option will terminate upon the expiration of such
period. For the purposes of this paragraph, the Option shall be considered
assumed if, following the merger or sale of assets, the option or right confers
the right to purchase, for each Share of Optioned Stock subject to the Option
immediately prior to the merger or sale of assets, the consideration (whether
stock, cash, or other securities or property) received in the merger or sale of
assets by holders of Common Stock for each Share held on the effective date of
the transaction (and if holders were offered a choice of consideration, the type
of consideration chosen by the holders of a majority of the outstanding Shares);
provided, however, that if such consideration received in the merger or sale of
assets was not solely common stock of the successor corporation or its Parent,
the Administrator may, with the consent of the successor corporation, provide
for the consideration to be received upon the exercise of the Option, for each
Share of Optioned Stock subject to the Option, to be solely common stock of the
successor corporation or its Parent equal in fair market value to the per share
consideration received by holders of Common Stock in the merger or sale of
assets.

         (d) Change in Control.   In the event of a Change in Control, the
             -----------------                                            
unexercised portion of the Option shall become immediately exercisable, to the
extent such acceleration does not disqualify the Plan, or cause an Incentive
Stock Option to be treated as a Nonstatutory Stock Option without the consent of
the Optionee.

     13.  Date of Grant.  The date of grant of an Option shall be, for all
          -------------                                                   
purposes, the date on which the Administrator makes the determination granting
such Option, or such other later date as is determined by the Administrator.
Notice of the determination shall be provided to each Optionee within a
reasonable time after the date of such grant.
<PAGE>
 
     14.  Amendment and Termination of the Plan.
          ------------------------------------- 

          (a) Amendment and Termination. The Board may at any time amend, alter,
              -------------------------     
suspend, or terminate the Plan.

          (b) Shareholder Approval. The Company shall obtain shareholder
              -------------------- 
approval of any Plan amendment to the extent necessary and desirable to comply
with Rule 16b-3 or with Section 422 of the Code (or any successor rule or
statute or other applicable law, rule, or regulation, including the requirements
of any exchange or quotation system on which the Common Stock is listed or
quoted). Such shareholder approval, if required, shall be obtained in such a
manner and to such a degree as is required by the applicable law, rule, or
regulation.

          (c) Effect of Amendment or Termination.  No amendment, alteration,
              ----------------------------------

which agreement must be in writing and signed by the Optionee and the Company.

     15.  Conditions Upon Issuance of Shares.
          ---------------------------------- 

          (a) Legal Compliance. Shares shall not be issued pursuant to the
              ----------------      
exercise of an Option unless the exercise of such Option and the issuance and
delivery of such Shares shall comply with all relevant provisions of law,
including, without limitation, the Securities Act of 1933, as amended, the
Exchange Act, the rules and regulations promulgated thereunder, Applicable Laws,
and the requirements of any stock exchange or quotation system upon which the
Shares may then be listed or quoted, and shall be further subject to the
approval of counsel for the Company with respect to such compliance.

          (b) Investment Representations.  As a condition to the exercise of an
              --------------------------                                       
Option, the Company may require the person exercising such Option to represent
and warrant at the time of any such exercise that the Shares are being purchased
only for investment and without any present intention to sell or distribute such
Shares if, in the opinion of counsel for the Company, such a representation is
required.

     16.  Liability of Company.
          -------------------- 

          (a) Inability to Obtain Authority. The inability of the Company to
              -----------------------------    
obtain authority from any regulatory body having jurisdiction, which authority
is deemed by the Company's counsel to be necessary to the lawful issuance and
sale of any Shares hereunder, shall relieve the Company of any liability in
respect of the failure to issue or sell such Shares as to which such requisite
authority shall not have been obtained.

          (b) Grants Exceeding Allotted Shares. If the Optioned Stock covered by
              --------------------------------     
an Option exceeds, as of the date of grant, the number of Shares which may be
issued under the Plan 
<PAGE>
 
without additional shareholder approval, such Option shall be void with respect
to such excess Optioned Stock, unless shareholder approval of an amendment
sufficiently increasing the number of shares subject to the Plan is timely
obtained in accordance with Section 14(b) of the Plan.

     17.  Reservation of Shares.  The Company, during the term of this Plan,
          ---------------------                                             
will at all times reserve and keep available such number of Shares as shall be
sufficient to satisfy the requirements of the Plan.

     18.  Shareholder Approval.  Continuance of the Plan shall be subject to
          --------------------                                              
approval by the shareholders of the Company within twelve (12) months before or
after the date the Plan is adopted.  Such shareholder approval shall be obtained
in the manner and to the degree required under applicable federal and Delaware
law.

advisable for administering the Plan.

           ---------------------------------                                    
the Administrator shall fix the period within which the Option may be exercised
and shall determine any conditions which must be satisfied before the Option may
be exercised.  In doing so, the Administrator may specify that an Option may not

       (c) Form of Consideration.  The Administrator shall determine the
           ---------------------                                        
acceptable form of consideration for exercising an Option, including the method

            (iii)  promissory note;

  10.  Exercise of Option.
       ------------------ 

       (a) Procedure for Exercise; Rights as a Shareholder.  Any Option granted
           -----------------------------------------------                     
thereunder shall be exercisable according to the terms of the Plan and at such
times and under such conditions as determined by the Administrator and set forth
in the Option Agreement.

           An Option may not be exercised for a fraction of a Share.

           An Option shall be deemed exercised when the Company receives:  (i)
written notice of exercise (in accordance with the Option Agreement) from the
person entitled to exercise the Option, and (ii) full payment for the Shares
with respect to which the Option is exercised.  Full payment may consist of any
consideration and method of payment authorized by the Administrator and
permitted by the Option Agreement and the Plan.  Shares issued upon exercise of
an Option shall be issued in the name of the Optionee or, if requested by the
Optionee, in the name of the Optionee and his or her spouse.  Until the Shares
are issued (as evidenced by the appropriate entry on the books of the Company or
of a duly authorized transfer agent of the Company), no right to vote or receive
dividends or any other rights as a shareholder shall exist with respect to the
Optioned Stock, notwithstanding the exercise of the Option.  The Company shall
issue (or cause to be issued) such Shares, promptly after the Option is
exercised.  No adjustment will be made for a dividend or other right for which
the record date is prior to the date the Shares are issued, except as provided
in Section 12 of the Plan.

           Exercising an Option in any manner shall decrease the number of
Shares thereafter available, both for purposes of the Plan and for sale under
the Option, by the number of Shares as to which the Option is exercised.

       (b) Termination of Employment or Consulting Relationship.  Upon
           ----------------------------------------------------       
termination of an Optionee's Continuous Status as an Employee or Consultant,
other than upon the Optionee's death or Disability, the Optionee may exercise
his or her Option, but only within such period of time as is specified in the
Notice of Grant, and only to the extent that the Optionee was entitled to
exercise it as the date of termination (but in no event later than the
expiration of the term of such Option as set forth in the Notice of Grant).  In
the absence of a specified time in the Notice of Grant, the Option shall remain
exercisable for 30 days following the Optionee's termination of Continuous
Status as an Employee or Consultant.  If, at the date of termination, the
Optionee is not entitled to exercise his or her entire Option, the Shares
covered by the unexercisable portion
<PAGE>
 
of the Option shall revert to the Plan. If, after termination, the Optionee does
not exercise his or her Option within the time specified herein, the Option
shall terminate, and the Shares covered by such Option shall revert to the Plan.

       (c) Disability of Optionee.  In the event that an Optionee's Continuous
           ----------------------                                             
Status as an Employee or Consultant terminates as a result of the Optionee's
Disability, the Optionee may exercise his or her Option at any time within
twelve (12) months from the date of such termination, but only to the extent
that the Optionee was entitled to exercise it at the date of such termination
(but in no event later than the expiration of the term of such Option as set
forth in the Notice of Grant).  If, at the date of termination, the Optionee
does not exercise his or her entire Option, the Shares covered by the
unexercisable portion of the Option shall revert to the Plan.  If, after
termination, the Optionee does not exercise his or her option within the time
specified herein, the Option shall terminate, and the Shares covered by such
Option shall revert to the Plan.

       (d) Death of Optionee.  In the event of the death of an Optionee, the
           -----------------                                                
Option may be exercised at any time within twelve (12) months following the date
of death (but in no event later than the expiration of the term of such Option
as set forth in the Notice of Grant), by the Optionee's estate or by a person
who acquired the right to exercise the Option by bequest or inheritance, but
only to the extent that the Optionee was entitled to exercise the Option at the
date of death.  If, at any time of death, the Optionee was not entitled to
exercise his or her entire Option, the Shares covered by the unexercisable
portion of the Option shall immediately revert to the Plan.  If, after death,
the Optionee's estate or a person who acquired the right to exercise the Option
by bequest or inheritance does not exercise the Option within the time specified
herein, the Option shall terminate, and the Shares covered by such Option shall

Administrator in the Option Agreement, an Option may not be sold, pledged,
assigned, hypothecated, transferred, or disposed of in any manner other than by

       -------------------------------------------------------------------------
Sale.
- ---- 

       (a) Changes in Capitalization.  Subject to any required action by the
           -------------------------                                        
shareholders of the Company, the number of shares of Common Stock covered by
each outstanding Option, and the number of issued shares of Common Stock which
have been authorized for issuance under the Plan but as to which no Options have
yet been granted or which have been returned to the Plan upon cancellation or
expiration of an Option, as well as the price per share of Common 
<PAGE>
 
Stock covered by each such outstanding Option, shall be proportionately adjusted
for any increase or decrease in the number of issued shares of Common Stock
resulting from a stock split, reverse stock split, stock dividend, combination
or reclassification of the Common Stock or any other increase or decrease in the
number of shares of Common Stock effected without receipt of consideration by
the Company; provided, however, that conversion of any convertible securities of
the Company shall not be deemed to have been effected without receipt of
consideration. Such adjustment shall be made by the Board, whose determination
in that respect shall be final, binding, and conclusive. Except as expressly
provided herein, no issuance by the Company of shares of stock of any class, or
securities convertible into shares of stock of any class, shall affect, and no
adjustment by reason thereof shall be made with respect to, the number or price
of shares of Common Stock subject to an Option.

       (b) Dissolution or Liquidation.  In the event of the proposed dissolution
           --------------------------                                           
or liquidation of the Company, to the extent that an Option has not been
previously exercised, it will terminate immediately prior to the consummation of
such proposed action.  The Board may, in the exercise of its sole discretion in
such instances, declare that any Option shall terminate as of a date fixed by
the Board and give each Optionee the right to exercise his or her Option as to
all or any part of the Optioned stock, including Shares as to which the Option
would not otherwise be exercisable.

       (c) Merger or Asset Sale.  In the event of a merger of the Company with
           --------------------                                               
or into another corporation, or the sale of substantially all of the assets of
the Company, each outstanding Option may be assumed or an equivalent option or
right may be substituted by the successor corporation or a Parent or Subsidiary
of the successor corporation.  The Administrator may, in lieu of such assumption
or substitution, provide for the Optionee to have the right to exercise the
Option as to all or a portion of the Optioned Stock, including Shares as to
which it would not otherwise be exercisable.  If the Administrator makes an
Option exercisable in lieu of assumption or substitution in the event of a
merger or sale of assets, the Administrator shall notify the Optionee that the
Option shall be fully exercisable for a period of thirty (30) days from the date
of such notice, and the Option will terminate upon the expiration of such
period.  For the purposes of this paragraph, the Option shall be considered
assumed if, following the merger or sale of assets, the option or right confers
the right to purchase, for each Share of Optioned Stock subject to the Option
immediately prior to the merger or sale of assets, the consideration (whether
stock, cash, or other securities or property) received in the merger or sale of
assets by holders of Common Stock for each Share held on the effective date of
the transaction (and if holders were offered a choice of consideration, the type
of consideration chosen by the holders of a majority of the outstanding Shares);
provided, however, that if such consideration received in the merger or sale of
assets was not solely common stock of the successor corporation or its Parent,
the Administrator may, with the consent of the successor corporation, provide
for the consideration to be received upon the exercise of the Option, for each
Share of Optioned Stock subject to the Option, to be solely common stock of the
successor corporation or its Parent equal in fair market value to the per share
consideration received by holders of Common Stock in the merger or sale of
assets.
<PAGE>
 
       (d) Change in Control.   In the event of a Change in Control, the
           -----------------                                            
unexercised portion of the Option shall become immediately exercisable.

  13.  Date of Grant.  The date of grant of an Option shall be, for all
       -------------                                                   
purposes, the date on which the Administrator makes the determination granting
such Option, or such other later date as is determined by the Administrator.

reasonable time after the date of such grant.

           ----------------------------------

exercise of an Option unless the exercise of such Option and the issuance and

then be listed or quoted, and shall be further subject to the approval of

only for investment and without any present intention to sell or distribute such
Shares if, in the opinion of counsel for the Company, such a representation is
required.

       --------------------                                                   
from any regulatory body having jurisdiction, which authority is deemed by the
Company's counsel to be necessary to the lawful issuance and sale of any Shares
hereunder, shall relieve the Company of any liability in respect of the failure
to issue or sell such Shares as to which such requisite authority shall not have
been obtained.

  17.  Reservation of Shares.  The Company, during the term of this Plan, will
       ---------------------

advisable for administering the Plan.

are issued (as evidenced by the appropriate entry on the books of the Company or
of a duly authorized transfer agent of the Company), no right to vote or receive
dividends or any other rights as a shareholder shall exist with respect to the
Optioned Stock, notwithstanding the exercise of the Option.  The Company shall
issue (or cause to be issued) such Shares, promptly after the Option is
exercised.  No adjustment will be made for a dividend or other right for which
the record date is prior to the date the Shares are issued, except as provided
in Section 12 of the Plan.

           Exercising an Option in any manner shall decrease the number of
Shares thereafter available, both for purposes of the Plan and for sale under
the Option, by the number of Shares as to which the Option is exercised.

       (b) Termination of Employment or Consulting Relationship.  Upon
           ----------------------------------------------------       
termination of an Optionee's Continuous Status as an Employee or Consultant,
other than upon the Optionee's death or Disability, the Optionee may exercise
his or her Option, but only within such period of time as is specified in the
Notice of Grant, and only to the extent that the Optionee was entitled to
exercise it as the date of termination (but in no event later than the
expiration of the term of such Option as set forth in the Notice of Grant).  In
the absence of a specified time in the Notice  of Grant, the Option shall remain
exercisable for 30 days following the Optionee's termination of Continuous
Status as an Employee or Consultant.  If, at the date of termination, the
Optionee is not entitled to exercise his or her entire Option, the Shares
covered by the unexercisable portion 
<PAGE>
 
of the Option shall revert to the Plan. If, after termination, the Optionee does
not exercise his or her Option within the time specified herein, the Option
shall terminate, and the Shares covered by such Option shall revert to the Plan.

       (c) Disability of Optionee.  In the event that an Optionee's Continuous
           ----------------------                                             
Status as an Employee or Consultant terminates as a result of the Optionee's
Disability, the Optionee may exercise his or her Option at any time within
twelve (12) months from the date of such termination, but only to the extent
that the Optionee was entitled to exercise it at the date of such termination
(but in no event later than the expiration of the term of such Option as set
forth in the Notice of Grant).  If, at the date of termination, the Optionee
does not exercise his or her entire Option, the Shares covered by the
unexercisable portion of the Option shall revert to the Plan.  If, after
termination, the Optionee does not exercise his or her option within the time
specified herein, the Option shall terminate, and the Shares covered by such
Option shall revert to the Plan.

       (d) Death of Optionee.  In the event of the death of an Optionee, the
           -----------------                                                
Option may be exercised at any time within twelve (12) months following the date
of death (but in no event later than the expiration of the term of such Option
as set forth in the Notice of Grant), by the Optionee's estate or by a person
who acquired the right to exercise the Option by bequest or inheritance, but
only to the extent that the Optionee was entitled to exercise the Option at the
date of death.  If, at any time of death, the Optionee was not entitled to
exercise his or her entire Option, the Shares covered by the unexercisable
portion of the Option shall immediately revert to the Plan.  If, after death,
the Optionee's estate or a person who acquired the right to exercise the Option
by bequest or inheritance does not exercise the Option within the time specified
herein, the Option shall terminate, and the Shares covered by such Option shall
revert to the Plan.

       (e) Suspension.   Any Optionee who is also a participant in the
           ----------                                                 
Retirement at Micron ("RAM") Section 401(k) Plan and who requests and receives a
hardship distribution from the RAM Plan, is prohibited from making, and must
suspend, his or her employee elective contributions and employee contributions
including, without limitation on the foregoing, the exercise of any Option
granted from the date of receipt by that employee of the RAM hardship
distribution.

  11.  Non-Transferability of Options.  Unless otherwise specified by the
       ------------------------------                                    
Administrator in the Option Agreement, an Option may not be sold, pledged,
assigned, hypothecated, transferred, or disposed of in any manner other than by
will or by laws of descent or distribution and may be exercised, during the
lifetime of the Optionee, only by the Optionee.

  12.  Adjustments Upon Changes in Capitalization, Dissolution, Merger, or Asset
       -------------------------------------------------------------------------
Sale.
- ---- 

       (a) Changes in Capitalization.  Subject to any required action by the
           -------------------------                                        
shareholders of the Company, the number of shares of Common Stock covered by
each outstanding Option, and the number of issued shares of Common Stock which
have been authorized for issuance under the Plan but as to which no Options have
yet been granted or which have been returned to the Plan upon cancellation or
expiration of an Option, as well as the price per share of Common 
<PAGE>
 
Stock covered by each such outstanding Option, shall be proportionately adjusted
for any increase or decrease in the number of issued shares of Common Stock
resulting from a stock split, reverse stock split, stock dividend, combination
or reclassification of the Common Stock or any other increase or decrease in the
number of shares of Common Stock effected without receipt of consideration by
the Company; provided, however, that conversion of any convertible securities of
the Company shall not be deemed to have been effected without receipt of
consideration. Such adjustment shall be made by the Board, whose determination
in that respect shall be final, binding, and conclusive. Except as expressly
provided herein, no issuance by the Company of shares of stock of any class, or
securities convertible into shares of stock of any class, shall affect, and no
adjustment by reason thereof shall be made with respect to, the number or price
of shares of Common Stock subject to an Option.

       (b) Dissolution or Liquidation.  In the event of the proposed dissolution
           --------------------------                                           
or liquidation of the Company, to the extent that an Option has not been
previously exercised, it will terminate immediately prior to the consummation of
such proposed action.  The Board may, in the exercise of its sole discretion in
such instances, declare that any Option shall terminate as of a date fixed by
the Board and give each Optionee the right to exercise his or her Option as to
all or any part of the Optioned stock, including Shares as to which the Option
would not otherwise be exercisable.

       (c) Merger or Asset Sale.  In the event of a merger of the Company with
           --------------------                                               
or into another corporation, or the sale of substantially all of the assets of
the Company, each outstanding Option may be assumed or an equivalent option or
right may be substituted by the successor corporation or a Parent or Subsidiary
of the successor corporation.  In the event that the successor corporation
refuses to assume or substitute the Option, the Optionee shall fully vest in and
have the right to exercise the Option as to all of the optioned stock.  If an
Option becomes fully vested and exercisable in lieu of assumption or
substitution in the event of a merger or sale of assets, the Administrator shall
notify the Optionee that the Option shall be fully exercisable for a period of
thirty (30) days from the date of such notice, and the Option will terminate
upon the expiration of such period.  For the purposes of this paragraph, the
Option shall be considered assumed if, following the merger or sale of assets,
the option or right confers the right to purchase, for each Share of Optioned
Stock subject to the Option immediately prior to the merger or sale of assets,
the consideration (whether stock, cash, or other securities or property)
received in the merger or sale of assets by holders of Common Stock for each
Share held on the effective date of the transaction (and if holders were offered
a choice of consideration, the type of consideration chosen by the holders of a
majority of the outstanding Shares); provided, however, that if such
consideration received in the merger or sale of assets was not solely common
stock of the successor corporation or its Parent, the Administrator may, with
the consent of the successor corporation, provide for the consideration to be
received upon the exercise of the Option, for each Share of Optioned Stock
subject to the Option, to be solely common stock of the successor corporation or
its Parent equal in fair market value to the per share consideration received by
holders of Common Stock in the merger or sale of assets.
<PAGE>
 
       (d) Change in Control.   In the event of a Change in Control, the
           -----------------                                            
unexercised portion of the Option shall become immediately exercisable.

  13.  Date of Grant.  The date of grant of an Option shall be, for all
       -------------                                                   
purposes, the date on which the Administrator makes the determination granting
such Option, or such other later date as is determined by the Administrator.
Notice of the determination shall be provided to each Optionee within a
reasonable time after the date of such grant.

  14.  Amendment and Termination of the Plan.
       ------------------------------------- 

       (a) Amendment and Termination.  The Board may at any time amend, alter,
           -------------------------                                          
suspend, or terminate the Plan.

       (b) Effect of Amendment or Termination.  No amendment, alteration,
           ----------------------------------                            
suspension, or termination of the Plan shall impair the rights of any Optionee,
unless mutually agreed otherwise between the Optionee and the Administrator,
which agreement must be in writing and signed by the Optionee and the Company.

  15.  Conditions Upon Issuance of Shares.
       ---------------------------------- 

       (a) Legal Compliance.  Shares shall not be issued pursuant to the
           ----------------                                             
exercise of an Option unless the exercise of such Option and the issuance and
delivery of such Shares shall comply with all Applicable Laws and the
requirements of any stock exchange or quotation system upon which the Shares may
then be listed or quoted, and shall be further subject to the approval of
counsel for the Company with respect to such compliance.

       (b) Investment Representations.  As a condition to the exercise of an
           --------------------------                                       
Option, the Company may require the person exercising such Option to represent
and warrant at the time of any such exercise that the Shares are being purchased
only for investment and without any present intention to sell or distribute such
Shares if, in the opinion of counsel for the Company, such a representation is
required.

  16.  Liability of Company.  The inability of the Company to obtain authority
       --------------------                                                   
from any regulatory body having jurisdiction, which authority is deemed by the
Company's counsel to be necessary to the lawful issuance and sale of any Shares
hereunder, shall relieve the Company of any liability in respect of the failure
to issue or sell such Shares as to which such requisite authority shall not have
been obtained.

  17.  Reservation of Shares.  The Company, during the term of this Plan, will
       ---------------------                                                  
at all times reserve and keep available such number of Shares as shall be
sufficient to satisfy the requirements of the Plan.

Applicable Laws.

      (c)  Powers of the Administrator.  Subject to the provisions of the Plan
           ---------------------------                                        
and, in the case of a Committee, the specific duties delegated by the Board to
such Committee, and subject to the approval of any relevant authorities,
including the approval, if required, of any stock exchange or national market
system upon which the Common Stock is then listed, the Administrator shall have
the authority, in its discretion:

           (i)    to determine the Fair Market Value of the Common Stock, in
accordance with Section 2(l) of the Plan;

           (ii)   to select the Consultants and Employees to whom Options may
from time to time be granted hereunder;

           (iii)  to determine whether and to what extent Options are granted
hereunder;

           (iv)   to determine the number of shares of Common Stock to be
covered by each such award granted hereunder;

           (v)    to approve forms of agreement for use under the Plan;
<PAGE>
 
           (vi)   to determine the terms and conditions, not inconsistent with
the terms of the Plan, of any award granted hereunder. Such terms and conditions
may include, but are not limited to, the exercise price, the time or times when
Options may be exercised, vesting provisions, the method of payment or
permissible methods of payment, any vesting acceleration or waiver of forfeiture
restrictions, and any restriction or limitation regarding any Option or the
Shares relating thereto, based in each case on such factors as the
Administrator, in its sole discretion, shall determine;

           (vii)  to reduce the exercise price of any Option to the then current
Fair Market Value if the Fair Market Value of the Common Stock covered by such
Option has declined since the date the Option was granted;

           (viii) to provide for the early exercise of Options for the purchase
of unvested Shares, subject to such terms and conditions as the Administrator
may determine; and

           (ix)   to construe and interpret the terms of the Plan and awards
granted pursuant to the Plan.

      (d) Effect of Administrator's Decision.  All decisions, determinations and
          ----------------------------------                                    
interpretations of the Administrator shall be final and binding on all Optionees
and any other holders of any Options.

   5. Eligibility.
      ----------- 

      (a) Nonstatutory Stock Options may be granted to Employees and
Consultants.  Incentive Stock Options may be granted only to Employees.  An
Employee or Consultant who has been granted an Option may, if otherwise
eligible, be granted additional Options.

      (b) Each Option shall be designated in the written option agreement as
either an Incentive Stock Option or a Nonstatutory Stock Option.  However,
notwithstanding such designation, for so long as the Code shall so provide, to
the extent that the aggregate Fair Market Value of the Shares with respect to
which Incentive Stock Options are exercisable for the first time by the Optionee
during any calendar year (under all plans of the Company and any Parent or
Subsidiary) exceeds $100,000, such Options shall be treated as Nonstatutory
Stock Options.

      For purposes of this Section 5(b), Incentive Stock Options shall be taken
into account in the order in which they were granted, and the Fair Market Value
of the Shares shall be determined as of the time the Option with respect to such
Shares is granted.

      (c) The Plan shall not confer upon any Optionee any right with respect to
the continuation of the Optionee's employment or consulting relationship with
the Company, nor shall it interfere in any way with the Optionee's right or the
Company's right to terminate the Optionee's employment or consulting
relationship at any time, with or without cause.
<PAGE>
 
      (d) The following limitations shall apply to grants of Options to
Employees:

          (i)   No Employee shall be granted, in any fiscal year of the Company,
Options to purchase more than 1,250,000 Shares.

          (ii)  In connection with his or her initial employment, an Employee
may be granted Options to purchase up to an additional 750,000 Shares which
shall not count against the limit set forth in subsection (i) above.

          (iii) The foregoing limitations shall be adjusted proportionately in
connection with any change in the Company's capitalization as described in
Section 11.

          (iv)  If an Option is cancelled in the same fiscal year of the Company
in which it was granted (other than in connection with a transaction described
in Section 11), the cancelled Option will be counted against the limit set forth
in subsection (i) above.  For this purpose, if the exercise price of an Option
is reduced, the transaction will be treated as a cancellation of the Option and
the grant of a new Option.

   6. Term of Plan.  The Plan shall become effective upon the earlier to occur
      ------------                                                            
of its adoption by the Board of Directors or its approval by the shareholders of
the Company, as described in Section 17 of the Plan.  It shall continue in
effect for a term of ten (10) years unless sooner terminated under Section 13 of
the Plan.

   7. Term of Option.  The term of each Option shall be the term stated in the
      --------------                                                          
Option Agreement; provided, however, that the term shall be no more than ten
(10) years from the date of grant thereof.  However, in the case of an Incentive
Stock Option granted to an Optionee who, at the time the Option is granted, owns
stock representing more than ten percent (10%) of the voting power of all
classes of stock of the Company or any Parent or Subsidiary, the term of the
Option shall be five (5) years from the date of grant thereof or such shorter
term as may be provided in the Option Agreement.

   8. Option Exercise Price and Consideration.
      --------------------------------------- 

      (a) The per share exercise price for the Shares to be issued pursuant to
exercise of an Option shall be such price as is determined by the Board, but
shall be subject to the following:

          (i)  In the case of an Incentive Stock Option:

               (A)  granted to an Employee who, at the time of the grant of
  such Incentive Stock Option, owns stock representing more than ten percent
  (10%) of the voting power of all classes of stock of the Company or any Parent
  or Subsidiary, the per Share exercise price shall be no less than 110% of the
  Fair Market Value per Share on the date of grant.
<PAGE>
 
               (B)  granted to any Employee other than an Employee
  described in the preceding paragraph, the per Share exercise price shall be no
  less than 100% of the Fair Market Value per Share on the date of grant.

          (ii)  In the case of a Nonstatutory Stock Option, the per share
exercise price shall be determined by the Administrator.

      (b) The consideration to be paid for the Shares to be issued upon exercise
of an Option, including the method of payment or permissible methods of payment,
shall be determined by the Administrator (and, in the case of an Incentive Stock
Option, shall be determined at the time of grant) and may consist of (1) cash,
(2) check, (3) promissory note, (4) other Shares which, in the case of Shares
acquired upon exercise of an Option, have been owned by the Optionee for more
than six months on the date of surrender and have a Fair Market Value on the
date of surrender equal to the aggregate exercise price of the Shares as to
which such Option shall be exercised, (5) delivery of a properly executed
exercise notice together with such other documentation as the Administrator and
the broker, if applicable, shall require to effect an exercise of the Option and
delivery to the Company of the sale or loan proceeds required to pay the
exercise price, or (6) any combination of the foregoing methods of payment.  In
making its determination as to the type of consideration to accept, the
Administrator may consider if acceptance of such consideration may be reasonably
expected to benefit the Company.

   9. Exercise of Option.
      ------------------ 

      (a) Procedure for Exercise; Rights as a Shareholder.  Any Option granted
          -----------------------------------------------                     
hereunder shall be exercisable at such times and under such conditions as
determined by the Administrator, including performance criteria with respect to
the Company and/or the Optionee, and as shall be permissible under the terms of
the Plan.

          An Option may not be exercised for a fraction of a Share.

          An Option shall be deemed to be exercised when written notice of such
exercise has been given to the Company in accordance with the terms of the
Option by the person entitled to exercise the Option and full payment for the
Shares with respect to which the Option is exercised has been received by the
Company.  Full payment may, as authorized by the Administrator, consist of any
consideration and method of payment allowable under Section 8(b) of the Plan.
Until the issuance (as evidenced by the appropriate entry on the books of the
Company or of a duly authorized transfer agent of the Company) of the stock
certificate evidencing such Shares, no right to vote or receive dividends or any
other rights as a shareholder shall exist with respect to the Optioned Stock,
notwithstanding the exercise of the Option.  The Company shall issue (or cause
to be issued) such stock certificate promptly upon exercise of the Option.  No
adjustment will be made for a dividend or other right for which the record date
is prior to the date the stock certificate is issued, except as provided in
Section 11 of the Plan.
<PAGE>
 
          Exercise of an Option in any manner shall result in a decrease in the
number of Shares which thereafter may be available, both for purposes of the
Plan and for sale under the Option, by the number of Shares as to which the
Option is exercised.

      (b)  Termination of Employment or Consulting Relationship.  Upon
           ----------------------------------------------------       
termination of an Optionee's Continuous Status as an Employee or Consultant,
other than upon the Optionee's death or Disability, the Optionee may exercise
his or her Option, but only within such period of time as is specified in the
Notice of Grant, and only to the extent that the Optionee was entitled to
exercise it at the date of termination (but in no event later than the
expiration of the term of such Option as set forth in the Notice of Grant).  In
the absence of a specified time in the Notice of Grant, the Option shall remain
exercisable 30 days following the Optionee's termination.  In the case of an
Incentive Stock Option, such period of time for exercise shall not exceed three
(3) months from the date of termination.  If, on the date of termination, the
Optionee is not entitled to exercise the Optionee's entire Option, the Shares
covered by the unexercisable portion of the Option shall revert to the Plan.
If, after termination, the Optionee does not exercise his or her Option within
the time specified by the Administrator, the Option shall terminate, and the
Shares covered by such Option shall revert to the Plan.

      Notwithstanding the above, in the event of an Optionee's change in status
from Consultant to Employee or Employee to Consultant, an Optionee's Continuous
Status as an Employee or Consultant shall not automatically terminate solely as
a result of such change in status.  However, in such event, an Incentive Stock
Option held by the Optionee shall cease to be treated as an Incentive Stock
Option and shall be treated for tax purposes as a Nonstatutory Stock Option
three months and one day following such change of status.

      (c) Disability of Optionee.  In the event of termination of an Optionee's
          ----------------------                                               
Continuous Status as an Employee or Consultant as a result of his or her
Disability, the Optionee may, but only within twelve (12) months from the date
of such termination (and in no event later than the expiration date of the term
of his or her Option as set forth in the Option Agreement), exercise the Option
to the extent the Optionee was otherwise entitled to exercise it on the date of
such termination.  To the extent that the Optionee is not entitled to exercise
the Option on the date of termination, or if the Optionee does not exercise the
Option to the extent so entitled within the time specified herein, the Option
shall terminate, and the Shares covered by the Option shall revert to the Plan.

      (d) Death of Optionee.  In the event of the death of an Optionee, the
          -----------------                                                
Option may be exercised at any time within twelve (12) months following the date
of death (but in no event later than the expiration of the term of such Option
as set forth in the Notice of Grant), by the Optionee's estate or by a person
who has acquired the right to exercise the Option by bequest or inheritance, but
only to the extent that the Optionee was entitled to exercise the Option at the
date of death.  If, at the time of death, the Optionee was not entitled to
exercise his or her entire Option, the Shares covered by the unexercisable
portion of the Option shall immediately revert to the Plan.  If, after death,
the Optionee's estate or a person who acquires the right to exercise the 
<PAGE>
 
Option by bequest or inheritance does not exercise the Option within the time
specified herein, the Option shall terminate, and the Shares covered by such
Option shall revert to the Plan.

      (e) Rule 16b-3.  Options granted to persons subject to Section 16(b) of
          ----------                                                         
the Exchange Act must comply with Rule 16b-3 and shall contain such additional
conditions or restrictions as may be required thereunder to qualify for the
maximum exemption from Section 16 of the Exchange Act with respect to Plan
transactions.

      (f) Suspension.  Any Optionee who is also a participant in the Retirement
          ----------                                                           
at Micron ("RAM") Section 401(k) Plan and who requests and receives a hardship
distribution from the RAM Plan, is prohibited from making, and must suspend for
a period of twelve months thereafter, his or her employee elective contributions
and employee contributions including, without limitation on the foregoing, the
exercise of any Option granted from the date of receipt by that employee of the
RAM hardship distribution.

   10.  Non-Transferability of Options.  Options may not be sold, pledged,
        ------------------------------                                    
assigned, hypothecated, transferred, or disposed of in any manner other than by
will or by the laws of descent or distribution and may be exercised, during the
lifetime of the Optionee, only by the Optionee.

   11.  Adjustments Upon Changes in Capitalization or Merger.
        ---------------------------------------------------- 

      (a) Changes in Capitalization.  Subject to any required action by the
          -------------------------                                        
shareholders of the Company, the number of shares of Common Stock covered by
each outstanding Option, and the number of shares of Common Stock which have
been authorized for issuance under the Plan but as to which no Options have yet
been granted or which have been returned to the Plan upon cancellation or
expiration of an Option, as well as the price per share of Common Stock covered
by each such outstanding Option, shall be proportionately adjusted for any
increase or decrease in the number of issued shares of Common Stock resulting
from a stock split, reverse stock split, stock dividend, combination or
reclassification of the Common Stock, or any other increase or decrease in the
number of issued shares of Common Stock effected without receipt of
consideration by the Company; provided, however, that conversion of any
convertible securities of the Company shall not be deemed to have been "effected
without receipt of consideration."  Such adjustment shall be made by the Board,
whose determination in that respect shall be final, binding and conclusive.
Except as expressly provided herein, no issuance by the Company of shares of
stock of any class, or securities convertible into shares of stock of any class,
shall affect, and no adjustment by reason thereof shall be made with respect to,
the number or price of shares of Common Stock subject to an Option.

      (b) Dissolution or Liquidation.  In the event of the proposed dissolution
          --------------------------                                           
or liquidation of the Company, the Administrator shall notify each Optionee as
soon as practicable prior to the effective date of such proposed transaction.
The Administrator in its discretion may provide for an Optionee to have the
right to exercise his or her Option until ten (10) days prior to such
transaction as to all of the Optioned Stock covered thereby, including Shares as
to which the 
<PAGE>
 
Option would not otherwise be exercisable. To the extent it has not been
previously exercised, an Option will terminate immediately prior to the
consummation of such proposed action.

      (c) Merger or Asset Sale.  In the event of a merger of the Company with or
          --------------------                                                  
into another corporation, or the sale of substantially all of the assets of the
Company, each outstanding Option shall be assumed or an equivalent option
substituted by the successor corporation or a Parent or Subsidiary of the
successor corporation.  In the event that the successor corporation refuses to
assume or substitute for the Option, the Optionee shall have the right to
exercise the Option as to all of the Optioned Stock, including Shares as to
which it would not otherwise be exercisable.  If an Option is exercisable in
lieu of assumption or substitution in the event of a merger or sale of assets,
the Administrator shall notify the Optionee that the Option shall be fully
exercisable for a period of fifteen (15) days from the date of such notice, and
the Option shall terminate upon the expiration of such period.  For the purposes
of this paragraph, the Option shall be considered assumed if, following the
merger or sale of assets, the option confers the right to purchase or receive,
for each Share of Optioned Stock subject to the Option immediately prior to the
merger or sale of assets, the consideration (whether stock, cash, or other
securities or property) received in the merger or sale of assets by holders of
Common Stock for each Share held on the effective date of the transaction (and
if holders were offered a choice of consideration, the type of consideration
chosen by the holders of a majority of the outstanding Shares); provided,
however, that if such consideration received in the merger or sale of assets was
not solely common stock of the successor corporation or its Parent, the
Administrator may, with the consent of the successor corporation, provide for
the consideration to be received upon the exercise of the Option, for each Share
of Optioned Stock subject to the Option, to be solely common stock of the
successor corporation or its Parent equal in fair market value to the per share
consideration received by holders of Common Stock in the merger or sale of
assets.

   12.  Time of Granting Options.  The date of grant of an Option shall, for all
        ------------------------                                                
purposes, be the date on which the Administrator makes the determination
granting such Option, or such other date as is determined by the Administrator.
Notice of the determination shall be given to each Employee or Consultant to
whom an Option is so granted within a reasonable time after the date of such
grant.

   13.  Amendment and Termination of the Plan.
        ------------------------------------- 

        (a) Amendment and Termination.  The Board may at any time amend, alter,
            -------------------------                                          
suspend or discontinue the Plan, but no amendment, alteration, suspension or
discontinuation shall be made which would impair the rights of any Optionee
under any grant theretofore made, without his or her consent.  In addition, to
the extent necessary and desirable to comply with Rule 16b-3 under the Exchange
Act or with Section 422 of the Code (or any other applicable law or regulation,
including the requirements of any stock exchange or national market system upon
which the Common Stock is then listed), the Company shall obtain shareholder
approval of any Plan amendment in such a manner and to such a degree as
required.
<PAGE>
 
        (b) Effect of Amendment or Termination. Any such amendment or
            ----------------------------------      
termination of the Plan shall not affect Options already granted, and such
Options shall remain in full force and effect as if this Plan had not been
amended or terminated, unless mutually agreed otherwise between the Optionee and
the Board, which agreement must be in writing and signed by the Optionee and the
Company.

   14.  Conditions Upon Issuance of Shares.  Shares shall not be issued pursuant
        ----------------------------------                                      
to the exercise of an Option unless the exercise of such Option and the issuance
and delivery of such Shares pursuant thereto shall comply with all relevant
provisions of law, including, without limitation, the Securities Act of 1933, as
amended, the Exchange Act, the rules and regulations promulgated thereunder, and
the requirements of any stock exchange or national market system upon which the
Common Stock is then listed or traded, and shall be further subject to the
approval of counsel for the Company with respect to such compliance.

      As a condition to the exercise of an Option, the Company may require the
person exercising such Option to represent and warrant at the time of any such
exercise that the Shares are being purchased only for investment and without any
present intention to sell or distribute such Shares if, in the opinion of
counsel for the Company, such a representation is required by any of the
aforementioned relevant provisions of law.

   15.  Reservation of Shares.  The Company, during the term of this Plan, shall
        ---------------------                                                   
at all times reserve and keep available such number of Shares as shall be
sufficient to satisfy the requirements of the Plan.

      The inability of the Company to obtain authority from any regulatory body
having jurisdiction, which authority is deemed by the Company's counsel to be
necessary to the lawful issuance and sale of any Shares hereunder, shall relieve
the Company of any liability in respect of the failure to issue or sell such
Shares as to which such requisite authority shall not have been obtained.

   16.  Agreements.  Options shall be evidenced by written agreements in such
        ----------                                                           
form as the Administrator shall approve from time to time.

   17.  Shareholder Approval.  Continuance of the Plan shall be subject to
        --------------------                                              
approval by the shareholders of the Company within twelve (12) months before or
after the date the Plan is adopted.  Such shareholder approval shall be obtained
in the degree and manner required under applicable state and federal law and the
rules of any stock exchange or national market system upon which the Common
Stock is then listed or traded.

RE:  MICRON QUANTUM DEVICES, INC. STOCK OPTIONS

     As you know, Micron Quantum Devices, Inc. ("MQD") entered into an Agreement
and Plan of Reorganization with Micron Technology, Inc. ("MTI").  Under the
Reorganization Agreement, MQD has merged with MTI, with MTI surviving the
Merger.

     In connection with this transaction, MTI has assumed all of your
outstanding options to purchase shares of common stock of MQD ("MQD Options").
As a result, your MQD Options are now options to purchase shares of common stock
of MTI rather than options to purchase shares of common stock of MQD.

     Each MQD Option assumed by MTI continues to be subject to the terms and
conditions, including vesting, set forth in the MQD 1996 Stock Option Plan and
as provided in the respective option agreements in effect immediately prior to
the Merger, except that (i) references to the "Company" in the MQD 1996 Stock
Option Plan are now references to MTI, and (ii) your options are now options to
purchase MTI common stock with the exercise price and number of shares subject
to your options adjusted to reflect the "conversion ratio" in the Merger, as
follows:

NUMBER OF SHARES SUBJECT TO MQD OPTIONS

   The number of shares of common stock of MTI subject to your MQD Options has
been adjusted to a number determined by multiplying .1133 by the number of
shares of MQD common stock that were issuable upon exercise of your option
immediately prior to the Merger, and rounding down to the nearest whole number.

NEW EXERCISE PRICE OF MQD OPTIONS

     The per share exercise price for shares of MTI common stock issuable upon
exercise of an assumed MQD Option has been adjusted to a price determined by
dividing the per share exercise price under your option in effect immediately
prior to the Merger by .1133 and rounding up to the nearest whole cent.
<PAGE>
 
     A summary of your converted stock options is attached and incorporated
herein by this reference.

     Further, any employment or consulting relationship with MQD referred to in
any MQD Option shall, from and after the Merger, be deemed to mean an employment
or consulting relationship with MTI as successor to all the rights and
obligations of MQD as a result of the Merger (including for purposes of vesting,
with prior employment by MQD treated as continuous employment by MTI).  Any
rights of first refusal provided in the applicable option exercise agreement or
documentation with respect to the MQD Options shall terminate in accordance with
the terms of the MQD Options or such documentation.

     If you have questions regarding the foregoing, please do not hesitate to
contact Bea Solis at (208) 368-4512 or Steve Suarez of MTI at (208) 368-4519.
After you have reviewed this letter, please acknowledge your agreement to the
assumption of your MQD Options on the terms set forth herein by signing the
enclosed copy of this letter and returning it to the attention of Steve Suarez
in the enclosed, postage pre-paid envelope attached.  Please keep a copy of this
letter and attach it to your existing option agreements in order for you to have
a complete record of all the terms and provisions applicable to your option as
now assumed by MTI.



                                Very Truly Yours,

                                MICRON TECHNOLOGY, INC.

     Re:  Registration Statement on Form S-8

Ladies and Gentlemen:

     We have examined the Registration Statement on Form S-8 to be filed by you
with the Securities and Exchange Commission on or about April 17, 1998 (the
"Registration Statement") in connection with the registration under the
Securities Act of 1933, as amended, of 32,687,307 shares of Common Stock, $0.10
par value per share, of Micron Technology, Inc., which shares may be issued
pursuant to the 1994 Stock Option Plan, Nonstatutory Stock Option Plan, 1997
Nonstatutory Stock Option Plan and Micron Quantum Devices, Inc. 1996 Stock
Option Plan all of which are filed as exhibits to the Registration Statement.
Such shares of Common Stock are referred to herein as the "Shares," and the
various employee stock option plans referenced above are collectively referred
to herein as the "Plans."  As your legal counsel in connection with this
transaction, we have examined the proceedings taken, and are familiar with the
proceedings proposed to be taken by you in connection with the issuance and sale
of the Shares pursuant to the Plans.

     It is our opinion that, when issued and sold in the manner described in the
Registration Statement and pursuant to the agreements which accompany each grant
under the Plans, and in accordance with the resolutions adopted by your Board of
Directors, the Shares will be legally and validly issued, fully-paid and non-
assessable.

     We consent to the use of this opinion as an exhibit to the Registration
Statement, and further consent to the use of our name wherever appearing in the
Registration Statement and any amendment thereto.

                                       Very truly yours,


                                       WILSON, SONSINI, GOODRICH & ROSATI
