                  LSI LOGIC PREPARES FOR RESUMPTION OF GROWTH;
       REDUCES COSTS IN RESPONSE TO GLOBAL SEMICONDUCTOR INDUSTRY DOWNTURN

MILPITAS, CALIFORNIA -- LSI Logic Corporation (NYSE: LSI) today reported 2001
second quarter revenues of $465 million, a 10 percent decrease from the $517
million reported in the first quarter, and 28 percent lower than the $644
million recorded in the second quarter of 2000.

The second quarter 2001 net loss, before amortization of goodwill and other
special items (EBG), was $20.9 million or minus 6 cents a diluted share,
compared to first quarter net income of $9.5 million or 3 cents a diluted share,
and second quarter 2000 net income of $98 million or 29 cents a diluted share.
Cash and short-term investments increased $82 million to $1.14 billion.

"Our second quarter financial results reflected the continuation of the
widespread inventory correction in the supply chain and weakened end-demand in
global communications and storage markets," said Wilfred J. Corrigan, LSI Logic
chairman and chief executive officer. "We expect our business to bottom in the
third quarter and anticipate revenue growth in the fourth quarter."

"During the second quarter, we completed the strategic acquisition of
consumer-products leader C-Cube and announced the purchase of AMI's RAID
business to expand our customer offerings in the storage components space. We
announced the closure of our Colorado Springs manufacturing facility and took
further steps to align our costs to the current business climate. We are
prepared to be an even stronger competitor in our targeted vertical markets when
the industry rebounds in 2002."

Bryon Look, LSI Logic executive vice president and chief financial officer, said
the company is taking approximately $292 million in charges, net of taxes. These
charges include: in-process research and development, amortization of
intangibles and non-cash deferred stock compensation, additional excess
inventory, restructuring of operations and other non-recurring and special items
resulting from the C-Cube transaction, earlier acquisitions, the closure of the
Colorado Springs manufacturing facility and a recent reduction in force.

"LSI Logic has taken necessary prudent actions in direct response to the global
semiconductor industry downturn," said Look. "We believe our cost-containment
actions, our strategic acquisitions and our advanced technology development
efforts put LSI Logic in a strong position to capitalize on the eventual
resumption of growth, driven by the communications, consumer and storage
markets."

                           LSI LOGIC BUSINESS OUTLOOK

LSI Logic expects 2001 Q3 revenues to decline approximately 10-15 percent
sequentially from the $465 million reported in the second quarter.

The company anticipates reporting a third quarter loss of about 31 cents a
diluted share on an EBG basis and a gross margin of approximately 30-32 percent,
reflecting a simultaneous bottoming in both revenues and factory utilization.

The company does not anticipate selling any equity investments in the third
quarter.

The 2001 tax rate is expected to be 0 percent.

Capital spending for 2001 is anticipated to be approximately $400 million.

Third quarter depreciation is projected to be about $83 million.

The third quarter diluted common share count will be approximately 365 million.

NOTE: The company's financial guidance will be limited to the comments made on
today's public conference call and contained in the Business Outlook section of
