               RECORD 2000 LSI LOGIC REVENUES EXCEED $2.7 BILLION
          BROADBAND, NETWORKING AND STORAGE DRIVE REVENUES AND PROFITS

MILPITAS, CALIFORNIA - LSI Logic Corporation (NYSE: LSI) today reported 2000
record revenues of $2.74 billion, a 31 percent increase over the $2.09 billion
in 1999.

Net income for 2000, before amortization of goodwill and other special items
(EBG), was $417 million or $1.21 a diluted share, a 140 percent increase over
the $174 million or 56 cents (split adjusted) a diluted share reported for 1999.
Cash and short term investments grew to $1.13 billion in 2000, up 71 percent
from $661 million in 1999.

"LSI Logic generated record revenues and earnings in 2000 despite a slowing
global economy in the second half of the year," said Wilfred J. Corrigan, LSI
Logic chairman and chief executive officer. "Presently, our customer base is
undergoing an inventory correction and there are some signs of decelerating end
demand.

"Looking forward, the global broadband market has clearly eased and networking
and storage components are experiencing inventory rebalancing. Once the
inventory buildup has been alleviated, we anticipate seeing a resumption of
growth toward the second half of the year for communications applications. While
the Sony PlayStation 2 is strong, other Broadband Entertainment businesses are
demonstrating their historical seasonality in the first quarter. Broadband
Entertainment is expected to rebound beginning in the second quarter. We
anticipate that Storage Components and SAN Systems will be strong in 2001.

"Based upon the current uncertainty in overall demand, our best estimate is for
LSI Logic to grow approximately 10 percent in 2001 with growth accelerating in
the second half of the year."

LSI Logic recorded $751 million in revenues for the 2000 fourth quarter, a 28
percent increase over the $585 million reported in the fourth quarter of 1999.
Fourth quarter 2000 revenues were 3.2 percent higher than the $728 million in
the third quarter, the 12th quarter of sequential revenue growth.

Fourth quarter 2000 EBG net income was $116 million or 34 cents a diluted share.
The fourth quarter EBG net income figure represented an increase of 52 percent
from the $76 million or 23 cents (split adjusted) a diluted share in the fourth
quarter of 1999. Cash and short term investments grew approximately $49 million
in the fourth quarter to $1.13 billion

                           LSI Logic Business Outlook

LSI Logic expects 2001 Q1 revenue to decline approximately 12 percent
sequentially from the $751 million reported in the fourth quarter.

   3

The company anticipates reporting first quarter earnings of 21 cents a diluted
share.

First quarter gross margin is expected to be comparable to the 43.8 percent in
the fourth quarter.

Recurring investment income will be around $5 million in the first quarter.

The 2001 tax rate is expected to be 25 percent.

Capital spending for 2001 is anticipated to be approximately $600 million,
unchanged from prior financial guidance.

First quarter depreciation is projected to be approximately $91 million.
