Exhibit 10.6

                       NATIONAL SEMICONDUCTOR CORPORATION

                           DIRECTOR STOCK OPTION PLAN

                    (as amended effective September 24, 1999)
         (adjusted to reflect the 2-for-1 stock split paid May 13, 2004)


1. PURPOSE

     The  purposes of the  Director  Stock  Option Plan (the "Plan") of National
Semiconductor  Corporation (the "Corporation") are to promote the recruiting and
retention  of  highly  qualified   individuals  to  serve  in  the  capacity  of
non-employee members of the Board of Directors of the Corporation  ("Directors")
and  to  strengthen   the   commonality  of  interest   between   Directors  and
stockholders.


2. NON-QUALIFIED OPTIONS

     It is intended that options to purchase  shares of the  Corporation's  $.50
par value  common  stock  (the  "Common  Stock")  granted  under this Plan shall
constitute non-qualified or non-statutory stock options, and not incentive stock
options within the meaning of Section 422A of the Internal Revenue Code of 1986,
as amended.


3. STOCK SUBJECT TO THE PLAN

     There will be reserved for issue upon the exercise of options granted under
the  Plan  2,000,000  shares  of the  Corporation's  Common  Stock,  subject  to
adjustment as provided in Paragraph 7, which may be unissued shares,  reacquired
shares,  or shares  bought on the  market.  If any option  which shall have been
granted shall expire or terminate for any reason  without  having been exercised
in full, the unpurchased shares shall again become available for the purposes of
the Plan (unless the Plan shall have been terminated).


4. ADMINISTRATION

     The  Plan  shall  be   administered  by  the  Board  of  Directors  of  the
Corporation,  whose  construction and interpretation of the terms and provisions
of the Plan shall be final and conclusive.  Grants of options under the Plan and
the  amount  and  nature of the  awards to be  granted  shall be  automatic  and
non-discretionary in accordance with Paragraph 6.


5. ELIGIBILITY

     Options may be granted only to non-employee Directors.



6. TERMS OF OPTION AND OPTION AGREEMENTS

     Each option shall be  evidenced by a written  agreement in such form as the
Board of  Directors  shall from time to time  approve,  which  agreements  shall
comply with and be subject to all of the applicable following provisions:

     (a) The  purchase  price  under each option  granted  shall be 100% of fair
market  value on the date of grant.  The fair market  value on the date of grant
shall be the opening price of the Common Stock on the New York Stock Exchange on
such  date (or if there  shall be no  trading  on such  date,  then on the first
previous date on which there was such trading).

     (b) Options shall be granted  automatically  and without  further action by
the Board of Directors to all eligible Directors as follows:  (i) on the date of
the  adoption  of the  Plan by the  Corporation's  stockholders,  each  eligible
Director  shall be granted an option to purchase  10,000 shares of Common Stock;
(ii) each person who becomes an eligible  Director after the date of adoption of
the Plan shall be granted an option to purchase 10,000 shares of Common Stock on
the date of the appointment of such person to the Board of Directors;  and (iii)
each eligible  Director shall be granted an additional option to purchase 10,000
shares of Common Stock on the date of each subsequent election of such person to
the Board of Directors by the stockholders.

     (c) The term of the  non-qualified  stock  options  granted under this Plan
shall be ten years and one day from the date the option was granted.

     (d) Options  shall  become fully  exercisable  six months after the date of
grant.

     (e) An option may not be exercised  to any extent,  either by the person to
whom it was granted, or by any person after his death, unless the person to whom
the option was granted has  remained  as a Director of the  Corporation  for not
less than six months from the date when the option was granted.

     (f) The Corporation, during the terms of options granted under the Plan, at
all times will keep  available the number of shares of stock required to satisfy
such options.

     (g) The Corporation will seek to obtain from each regulatory  commission or
agency having  jurisdiction  such authority as may be required to issue and sell
shares of stock to satisfy such options.  Inability of the Corporation to obtain
from any such  regulatory  commission or agency  authority which counsel for the
Corporation  deems  necessary  for the lawful  issuance and sale of its stock to
satisfy  such options  shall  relieve the  Corporation  from any  liability  for
failure to issue and sell stock to satisfy  such  options  pending the time when
such authority is obtained or is obtainable.

     (h)  Neither  a  person  to  whom  an  option  is  granted  nor  his  legal
representative,  heir, legatee, or distributee, shall be deemed to be the holder
of, or to have any of the rights of a holder with respect to, any shares subject
to such  option  unless and until he has  exercised  his option  pursuant to the
terms thereof.


     (i) An option  shall not be  transferable  except by will or by the laws of
descent  and  distribution,  and during the  lifetime  of the person to whom the
option is granted he alone may exercise it.

     (j) An option  shall  terminate  and may not be  exercised if the person to
whom it is granted ceases to be a Director of the  Corporation,  except (subject
nevertheless to the last sentence of this  subparagraph  (j)): (1) if his status
as a Director  is  terminated  for any reason  other than (i)  retirement,  (ii)
permanent  disability,  or (iii) death, he may exercise his option to the extent
that he was entitled to exercise such option at the date of such  termination at
any  time  within  a  period  of three  (3)  months  following  the date of such
termination,  or if he shall die within the period of three (3) months following
the date of such termination  without having  exercised such option,  his option
may be exercised  within a period of one year  following his death by the person
or persons to whom his  rights  under the option  pass by will or by the laws of
descent or distribution  but only to the extent  exercisable at the date of such
termination; or (2) if his status as a Director is terminated by (i) retirement,
(ii)  permanent  disability,  or (iii)  death,  his option may be  exercised  in
accordance with its terms and conditions at any time within a period of five (5)
years  following  the date of such  termination  by him,  or in the event of his
death,  by the persons to whom his rights under the option shall pass by will or
by the laws of descent or distribution.  Nothing  contained in this subparagraph
(j) is  intended  to extend the stated term of the option and in no event may an
option be exercised by anyone after the expiration of its stated term.

     (k) Nothing in this Plan or in any option granted hereunder shall confer on
any optionee any right to continue as a Director of the Corporation.

     (l) If an option  agreement is not executed by the optionee and returned to
the  Corporation  on or prior to ninety  (90) days  after the date the option is
granted, such option shall terminate.

     (m) The following definitions shall apply for purposes of this Plan:

          (1)  "retirement":  termination  as  a  Director  after  reaching  age
               sixty-five  (65) or after  reaching age  fifty-five  (55) and the
               optionee's  age plus years of service as a Director is sixty-five
               (65) or more;

          (2)  "permanent  disability":  a  permanent  and total  incapacity  to
               perform any services as a Director.


7. ADJUSTMENT IN NUMBER OF SHARES AND IN OPTION PRICE

     In the event there is any change in the shares of the  Corporation  through
the   declaration  of  stock   dividends  or  a  stock   split-up,   or  through
recapitalization  resulting in share split-ups,  or combinations or exchanges of
shares, or otherwise,  the number of shares available for option, as well as the
shares  subject  to  any  option  and  the  option  price   thereof,   shall  be
appropriately adjusted, provided that the number of shares subject to any option
shall always be a whole number.


8. PAYMENT OF PURCHASE PRICE AND WITHHOLDING TAXES

     (a) The  purchase  price  for all  shares  purchased  pursuant  to  options
exercised  must be either paid in full in cash,  or paid in full in Common Stock
of the  Corporation and valued at fair market value on the date of exercise or a
combination of cash and Common Stock.  Fair market value on the date of exercise
is the opening price of the Common Stock on the New York Stock  Exchange on such
date, or if there shall be no trading on such date,  then on the first  previous
date on which there was such trading.

     (b) All or part of  required  withholding  taxes  that  may be due upon the
exercise of an option,  up to the highest marginal rates then in effect,  may be
paid by the  withholding  of shares  otherwise  issuable  upon  exercise  of the
option.  Option shares  withheld in payment of such taxes shall be valued at the
fair market value of the  Corporation's  Common Stock on the date of exercise as
defined herein.


9. AMENDMENT, SUSPENSION, OR TERMINATION OF THE PLAN

     (a) The Board may  amend,  modify,  suspend or  terminate  the Plan for the
purpose of meeting or addressing  any changes in legal  requirements  or for any
other  purpose  permitted by law;  provided,  however,  that the  provisions  of
Paragraphs  5,  6(a),  6(b),  6(c),  6(d),  6(e) and 6(j) of the Plan may not be
amended  more than once every six months,  other than to comport with changes in
the Internal Revenue Code of 1986, as amended,  the Employee  Retirement  Income
Security Act, or the rules thereunder.  The Board will seek stockholder approval
of an amendment if determined to be required by or advisable  under  regulations
of the Securities and Exchange  Commission or the Internal Revenue Service,  the
rules of any stock exchange on which the Corporation's  stock is listed or other
applicable law or regulation.

     (b) The Plan shall continue in effect unless sooner  terminated.  An option
may not be granted while the Plan is suspended or after it is terminated.

     (c) Subject to the  limitations of Paragraph 9, the rights and  obligations
under any options  granted  while the Plan is in effect  shall not be altered or
impaired by amendment,  suspension or termination  of the Plan,  except with the
consent of the person to whom the option was granted or to whom rights  under an
option shall have passed by will or by the laws of descent and distribution.


10. EFFECTIVE DATE

     The Plan shall become  effective  on June 26, 1997,  subject to approval by
the  stockholders  of the  Corporation  within twelve months after such date. No
option shall be granted  under the Plan until the Plan has been  approved by the
stockholders of the Corporation.
