EXHIBIT 99.1



     STATEMENT UNDER OATH OF PRINCIPAL EXECUTIVE OFFICER REGARDING FACTS AND
                 CIRCUMSTANCES RELATING TO EXCHANGE ACT FILINGS

I, Wilfred J. Corrigan, state and attest that:

(1) To the best of my knowledge, based upon a review of the covered reports of
LSI Logic Corporation, and, except as corrected or supplemented in a subsequent
covered report:

    -   no covered report contained an untrue statement of a material fact as of
        the end of the period covered by such report (or in the case of a report
        on Form 8-K or definitive proxy materials, as of the date on which it
        was filed); and

    -   no covered report omitted to state a material fact necessary to make the
        statements in the covered report, in light of the circumstances under
        which they were made, not misleading as of the end of the period covered
        by such report (or in the case of a report on Form 8-K or definitive
        proxy materials, as of the date on which it was filed).

(2) I have reviewed the contents of this statement with the Company's audit
committee.

(3) In this statement under oath, each of the following, if filed on or before
the date of this statement, is a "covered report":

    -   LSI Logic Corporation's Annual Report on Form 10-K filed with the
        Commission for the year ended December 31, 2001.

    -   All Quarterly Reports on Form 10-Q, Current Reports on Form 8-K and all
        Definitive Proxy materials filed with the Commission by LSI Logic
        Corporation after the filing of the Annual Report on Form 10-K
        identified above.

    -   Any amendments to any of the foregoing.
