EXHIBIT 10.55

                    AMENDED AND RESTATED EMPLOYMENT AGREEMENT
                    -----------------------------------------

         This Amended and Restated Employment Agreement (the "Agreement") is
entered into by and between Advanced Micro Devices, Inc. ("AMD") and Hector Ruiz
("Executive"). AMD and Executive may be referred to collectively in the
Agreement as the "Parties."

         WHEREAS, AMD and Executive entered into that certain Employment
Agreement dated January 13, 2000 (the "Original Employment Agreement"); and

         WHEREAS, the Original Employment Agreement was supplemented by that
certain First Supplement to Employment Contract dated December 22, 2000, by and
between the Parties, as such First Supplement to Employment Contract was
subsequently amended by agreement of the Parties (such First Supplement to
Employment Contract as amended being collectively referred to herein as the
"Supplement"); and

         WHEREAS, AMD and Executive desire to amend and restate the Original
Employment Agreement and the Supplement, and in connection therewith, to
incorporate the provisions of the Original Employment Agreement, as amended and
restated, and the Supplement, as amended and restated, into one agreement, all
as hereinafter provided;

         NOW, THEREFORE, in consideration of the premises and the mutual
covenants and agreements herein contained, the Parties agree as follows:

         1. Position. Executive will be employed by AMD as its President and
            --------
Chief Operating Officer, effective commencing upon the date of Executive's
resignation from his immediately prior employer (the "Commencement Date"),
reporting directly to W. J. Sanders III. During his AMD employment, Executive
will also be a member of the Office of the CEO. Executive will be elected to the
AMD Board of Directors at the first scheduled Board Meeting following the
Commencement Date. During the term of his employment, Executive will be expected
to devote his full working time and attention to the business of AMD, and he
will not render services to any other business without the prior approval of the
Board of Directors, or, directly or indirectly, engage or participate in any
business that is competitive in any manner with the business of AMD.
Notwithstanding the foregoing, Executive may remain a director of businesses
with respect to which he is a director on the Commencement Date. Executive will
also be expected to comply with and be bound by AMD's operating policies,
procedures and practices that are from time to time in effect during the term of
his employment.

         2. Base Salary. Executive's initial base annual salary will be
            -----------
$750,000, payable in accordance with AMD's normal payroll practices with such
payroll deductions and withholdings as are required by law. Executive's base
salary will be reviewed on an annual basis by the Compensation Committee of the
Board of Directors and increased in April 2001 and from time to time thereafter,
in the discretion of the Board of Directors.

          3. Bonus. Executive's bonus each year will be equal to 0.3% of AMD's
             -----
Adjusted Operating Profit ("AOP") for that fiscal year in excess of 20% of AMD's
AOP for the



immediately preceding fiscal year, subject to a maximum award of $5M in any
year. Since AMD will report a loss for 1999, Executive's bonus for FY2000 will
be equal to 0.3% of AOP for FY2000. AMD will guarantee that Executive's FY2000
bonus will be no less than $500,000.

         4.  Stock Options.
             -------------

                  a. On the Commencement Date, the Compensation Committee of the
         Board of Directors shall grant Executive a nonqualified stock option to
         purchase 1,000,000 shares of AMD common stock at an exercise price
         equal to the closing price of the common stock on the Commencement Date
         (the "Initial Option"), the schedule of which is attached as Exhibit A.
                                                                      ---------
         This Initial Option will vest and become exercisable over a four-year
         period, with 250,000 shares vesting and becoming exercisable on each
         anniversary of the Commencement Date.

                  b. Commencing in April 2001, Executive will be granted
         annually nonqualified stock options to purchase 250,000 shares of AMD
         common stock at an exercise price equal to the closing price of the
         common stock on the grant date (the "Additional Options"). These
         Additional Options will each vest in two equal annual installments such
         that Executive will vest in 250,000 shares of AMD common stock each
         year commencing in 2005.

         5.       Retirement Benefit Replacement.
                  ------------------------------

                  a. Lump Sum Benefit. On or before the time Executive attains
                     ----------------
         age 57 on December 25, 2002, AMD will provide him with a lump sum cash
         benefit of $3,727,020 (the "Retirement Benefit Amount" or "RBA"), which
         is estimated to be the current projected benefit available to Executive
         under the Motorola Executive Incentive Plan.

                  b. Payment of RBA to Executive.  The RBA will be paid as
                     ---------------------------
                  follows:

                     (i)   Establishment of Trust. Upon Executive's attainment
                           ----------------------
                    of age 55 in December of 2000, AMD will establish a secular
                    trust in Executive's name (the "Trust") pursuant to a Trust
                    Agreement for the Hector Ruiz/Advanced Micro Devices, Inc.
                    Supplemental Retirement Benefit (the "Trust Agreement")
                    among AMD, Executive and Wells Fargo Bank, N.A. ("Trustee").

                     (ii)  Partial Payment of RBA Into the Trust. In January of
                           -------------------------------------
                    2001, Executive shall have the right, without restriction,
                    to receive a lump sum payment from AMD in the amount of
                    $3,200,000, as partial payment of the RBA. Executive hereby
                    directs that at such time, AMD, as Executive's agent, shall
                    deposit such lump sum payment with the Trustee. Upon such
                    deposit, such lump sum payment shall become the principal of
                    the Trust under the Trust Agreement.

                                       2



                           (iii) Payment of Entire RBA Amount. Payments to
                                 ----------------------------
                  Executive of the principal of the Trust and any income or
                  earnings on amounts held in the Trust shall be made at such
                  times and in such amounts as provided in the Trust Agreement.
                  If after such payments have been made to Executive the
                  aggregate amount of such payments is less than the RBA, AMD
                  agrees to pay to Executive on the date of the last of such
                  payments the amount of such deficiency, so that on such date
                  Executive has received the total RBA.

                  c.       Reimbursement to Executive for Certain Tax
                           ------------------------------------------
          Liabilities. Within thirty (30) days after the end of each calendar
          -----------
          quarter of the calendar years 2001 and 2002 (each, a "Quarter"), AMD
          will pay directly to, or on behalf and for the benefit of, Executive
          an amount equal to the "Tax Reimbursement Payment" (as hereinafter
          defined) with respect to any amounts paid by AMD to the Trust during
          such Quarter (which amounts shall, in the case of the first calendar
          quarter of 2001, include, without limitation, the deposit made with
          the Trustee pursuant to Section 5(b)(ii)), any income or earnings
          during such Quarter on amounts held in the Trust, and/or any payments
          by AMD to Executive during such Quarter with respect to the RBA
          (collectively, the "Taxable Income Inclusion"). Any Tax Reimbursement
          Payment will be included in Executive's IRS Form W-2 for the year in
          which payment thereof is made to, or on behalf and for the benefit of,
          Executive. The schedule for the Tax Reimbursement Payments is:

                  The amount of a "Tax Reimbursement Payment" for a Quarter
         shall be equal to an amount equal to the excess of (i) an amount
         determined by dividing (A) the amount of the Taxable Income Inclusion
         for such Quarter, by (B) one minus the sum of the following expressed
         as a decimal: (I) the highest Federal individual marginal income tax
         rate for the calendar year which includes such Quarter, plus (II) the
         highest state individual marginal income tax rate to which such Taxable
         Income Inclusion is subject for the calendar year which includes such
         Quarter, plus (III) the Hospital (Medicare) Insurance tax rate under
         3101(b) of the Internal Revenue Code of 1986, as amended (the "Code"),
         or any corresponding successor statute, that is in effect for such
         Quarter, over (ii) the amount of such Taxable Income Inclusion.

                  d.       Amount Payable By Executive to AMD.  If Executive
                           ----------------------------------

         Payments, whether from the Trust and/or AMD, prior to his attainment of
         age 57, and

                                       3



         Executive's employment hereunder is terminated by AMD for "Cause" (as
         hereinafter defined), then Executive agrees to pay to AMD the amount
         of such payments, including any Tax Reimbursement Payments made
         directly to Executive or on his behalf, as follows: (i) to the extent
         such payment(s) is/are received by Executive on or before the date of
         such termination, Executive shall pay the amount of such paymen(s) to
         AMD within three business days after the date of such termination, and
         (ii) to the extent such payment(s) is/are received by Executive after
         the date of such termination, Executive shall pay the amount of such
         payment(s) to AMD within three business days after the date of such
         receipt. If Executive receives payment(s) from the Trust in excess of
         the RBA at his attainment of age 57, he agrees to pay to AMD within
         three business days of his receipt of such payment(s) an amount equal
         to such excess.

         pay to Executive an amount necessary to place him in the same after-tax
         position as he would have been in had no such excise tax been imposed.
         The amount payable pursuant to the preceding sentence shall be
         increased to the extent necessary to pay income and excise taxes due on
         such amount. The determination of the amount of any such tax indemnity
         shall be made by the independent accounting firm employed by AMD
         immediately prior to the Change of Control.

                                       6



                  d.  No payments due to Executive under this Section 9 shall be

                  a. In the event Executive forfeits any portion of his Motorola
         1999 Annual Bonus, AMD will pay an equivalent amount to him (not to
         exceed $500,000) on the date Executive provides evidence of such
         forfeiture.

                  b. In the event Executive forfeits any gains attributable to
         his 46,667 vested Motorola stock options, AMD will pay an amount to him
         equal to the lesser of (i) the aggregate amount of the forfeiture by
         him of such gains or (ii) the aggregate spread on shares subject to the
         option based on the difference between $52 per share and the closing
         price of Motorola common stock on the New York Stock Exchange on the
         Commencement Date, in either case on the date Executive provides
         evidence of such forfeiture.

                  c. Executive shall be required to make reasonable efforts
         (including, but not limited to, at the request of AMD after
         consultation with him, commencement of litigation for which AMD will
         pay reasonable costs) to avoid the above forfeitures or to reinstate
         any forfeited benefits, and he shall be required to reimburse AMD if
         such amounts are subsequently reinstated by Motorola.

                  d. In the event of a Voluntary Termination or Termination for
         Cause within two years of the Commencement Date, Executive shall be
         required to repay the full amount of any payments by AMD pursuant to
         this Section 10.

         11. Confidential Information and Invention Assignment Agreement. Upon
             -----------------------------------------------------------
Executive's commencement of employment with AMD, he will be required to sign
AMD's standard form of Nondisclosure Agreement to protect AMD's confidential
information and intellectual property.

         12. Nonsolicitation. During the term of Executive's employment with AMD
             ---------------
and for one year thereafter, he will not, on behalf of himself or any third
party, solicit or attempt to induce any employee of AMD to terminate his or her
employment with AMD.

         13. Arbitration. The Parties agree that any dispute regarding the
             -----------
interpretation or enforcement of this Agreement shall be decided by
