PATRIOT SCIENTIFIC CORPORATION

PATENT PORTFOLIO LICENSE AGREEMENT

THIS AGREEMENT made and entered into this February 21, 2005 (the Effective Date)
by and between Patriot Scientific Corp., a Delaware corporation having an office
at 10989 Via Frontera, San Diego, California 92127 (hereinafter "PTSC") and
Advanced Micro Devices Inc. a Delaware corporation, having an office at 5204
East Ben White, Austin, Texas 78741 (hereinafter "Licensee") including Spansion
Inc. and all current Affiliates of AMD and Affiliates formed by AMD over the
course of this Agreement for which AMD owns or controls more than 50% of the
shares, board seats, or equity in the entity. This Agreement shall apply to all
current AMD Affiliates, in the same manner it applies to AMD, for the term of
this Agreement even if these legal entities cease in the future to be an
"Affiliate" of AMD, as defined above.

WHEREAS, PTSC owns certain U.S. patent rights, as defined herein, relating
to high performance, low cost microprocessors and has the right to enter
into the Agreement and grant the license granted herein;

WHEREAS, PTSC is involved in litigation to enforce PTSC Patent Rights
(defined herein) in the U.S. District Court for the Northern District of
California (PTSC v. Fujitsu et al, No. C035787SBA and Intel v. PTSC, No.
C040439SBA) and to correct inventorship of same (PTSC v. Moore et al, No.
C0400618JF) (the "Pending Litigations").

WHEREAS, Licensee desires to obtain a license to PTSC Patent Rights to
avoid litigation and has the right to enter into this Agreement; and

WHEREAS, PTSC is willing to grant Licensee such an license upon the terms
and conditions set forth herein.

NOW, THEREFORE, intending to be legally bound, the parties hereto agree as
follows:

1.0 -- PTSC Patent Rights

1.1 "Other Patents" shall mean all Patents, not including the patents
covered by PTSC Patent Rights, in any country of the world including all
reissues, divisions, renewals, reexaminations, extensions, provisionals,
continuations, continuing prosecution applications and
continuations-in-part thereof, in each case then owned (in whole or in
part) or otherwise controlled by PTSC. Other Patents shall include all
Patents to which PTSC has the right to grant sublicenses at any time up
until five years from the Effective Date of this Agreement, provided,
however, that if such right to grant sublicenses is subject to payment to
a third party (other than a PTSC Subsidiary, agent, or an employee of PTSC
or a PTSC Subsidiary), such Patent or patentable invention will be deemed
to be a Licensed Patent only if LICENSEE agrees to bear such payment or
otherwise arranges terms with the third party that removes the obligation
of payment on PTSC.

1.2 "PTSC Patent Rights" shall mean: the U.S. Patents listed in Appendix A
attached hereto and made a part hereof and any continuation,
continuation-in-part or divisional of any such application, the patents
issuing thereon, and any reissue, reexamination or extension of any such
patent, and any patent application or patent corresponding to such patents
which are filed or hereinafter issued in any country;

1.3 "Patents" shall mean all classes and types of patents, design patents,
utility models, invention disclosures, or like instruments conferring
similar rights (filed or issued) and all applications therefore in all
countries of the world.

2.0 -- Confidentiality

2.1 Confidential Information. For a period of seven (7) years following
first disclosure thereof, each party shall maintain in confidence the
confidential information of the other party (including samples) disclosed
by the other party and identified as, or acknowledged to be confidential
(the "Confidential Information") at the time of disclosure, and shall not
use, disclose or grant the use of the Confidential Information except as
licensed herein or on a need-to-know basis to those directors, officers,
affiliates, employees, permitted licensees, permitted assignees and
agents, consultants, clinical investigators, contractors, or other people
or entities reasonably needed in connection with such party's activities
as expressly authorized by the Agreement. To the extent that disclosure is
authorized by the Agreement, prior to disclosure, each party hereto shall
obtain agreement of any such Persons to hold in confidence and not make
use of the Confidential Information for any purpose other than those
permitted by the Agreement.

2.2 Permitted Disclosures. Except as otherwise set forth in Section 7.2
herein, the confidentiality obligations contained in Section 2.1 above
shall not apply to the extent that (a) any receiving party (the
"Recipient") is required (i) to disclose information by law, order or
regulation of a governmental agency or a court of competent jurisdiction,
or (ii) to disclose information to any governmental agency for purposes of
obtaining approval to test or market a product, provided in either case
that the Recipient shall provide written notice thereof to the other party
and sufficient opportunity to object to any such disclosure or to request
confidential treatment thereof; or (b) the Recipient can demonstrate that


(i) the disclosed information was public knowledge at the time of such
disclosure to the Recipient, or thereafter became public knowledge, other
than as a result of actions of the Recipient in violation hereof; (ii) the
disclosed information was rightfully known by the Recipient (as shown by
its written records) prior to the date of disclosure to the Recipient by
the other party hereunder; or (iii) the disclosed information was
disclosed to the Recipient on an unrestricted basis from a source
unrelated to any party to the Agreement and not under a duty of
confidentiality to the other party.

2.3 Terms of the Agreement. Except as otherwise provided in Section 2.2
and Section 7.2 hereof, or as required in order to operate in accordance
with applicable laws and regulations (e.g., disclosure to legal counsel,
accounting firms, etc.), LICENSEE shall not disclose any terms or
conditions of the Agreement to any third party without the prior consent
of PTSC. Notwithstanding the foregoing, during the term of this Agreement,
LICENSEE may disclose that it holds a non-exclusive license to PTSC
Patents Rights and Other Patents.

2.4 Proprietary Rights. All ownership of patent rights, copyrights, trade
secret rights and other proprietary rights in the PTSC Patent Rights and
Other Patents shall remain with PTSC and their licensors, and no right or
license is granted to LICENSEE hereunder except for the non-exclusive
grants and covenants expressly set forth in Section 4.1 (a), (b), (c), and


(d) hereof.

Rights.

damages it may have against Licensee and its customers for past
infringement of PTSC Patent Rights or Other Patents.

that are not LICENSEE or Affiliates of LICENSEE as set forth herein obtain
no benefit from the license rights and covenants set forth herein unless:

for AMD so that AMD can exercise its rights under this Agreement or the

then the licenses and covenants applicable to these entities under this
Agreement shall extend only to the work done in conjunction with AMD; or


(ii) these parties have bought a product or service from AMD that is
licensed herein and/or subject to a covenant under this Section 4, in
