ITEM 7. FINANCIAL STATEMENTS AND EXHIBITS.

        (a)   Financial statements of business acquired. Not applicable.

        (b)   Pro forma financial information. Not applicable.

        (c)   Exhibits. The exhibit listed below is being furnished with this
              Form 8-K.

              Exhibit 99.1   Press Release dated as of January 22, 2004 entitled
                             "Cypress Reports Fourth Quarter 2003 Results."

ITEM 9. REGULATION FD DISCLOSURE

     In accordance with SEC Release No. 33-8216, the following information
(including any exhibits attached to this Current Report on Form 8-K) is
furnished pursuant to Item 12, "Disclosure of Results of Operations and
Financial Condition."

     On January 22, 2004, Cypress Semiconductor Corporation issued a press
release announcing its results for the fiscal quarter ended December 28, 2003.
The press release is attached to this Current Report on Form 8-K as Exhibit
99.1.

                      USE OF NON-GAAP FINANCIAL INFORMATION

     Cypress provides certain non-GAAP financial measures as additional
information relating to its operating results. Cypress's management believes
that the presentation of these measures provides useful information to investors
regarding certain additional financial and business trends relating to its
financial condition and results of operations. These measures are not in
accordance with, or an alternative to, generally accepted accounting principles
and may be different from non-GAAP measures used by other companies. The
calculations of non-GAAP net income (loss) have been adjusted to exclude the
effects of acquisition-related costs, restructuring charges, impairments, asset
write-downs, amortization of intangibles, gains on bond retirement and certain
employee loan reserves and to reflect the tax effects of these adjustments.

     Pursuant to the requirements of Regulation G, we have provided a
reconciliation of the non-GAAP financial measures to the most directly
comparable GAAP financial measures.

     The information in this report, including the exhibit hereto, shall not be
deemed to be "filed" for purposes of Section 18 of the Securities Exchange Act
of 1934, as amended, or otherwise subject to the liability of that section. The
information contained herein and in the accompanying exhibit shall not be
incorporated by reference into any filing with the U.S. Securities and Exchange
Commission made by Cypress, whether made before or after the date hereof,
regardless of any general incorporation language in such filing.

                                       -2-


                                    SIGNATURE

     Pursuant to the requirements of the Securities Exchange Act of 1934, the
registrant has duly caused this report to be signed on its behalf by the
undersigned hereunto duly authorized.
