      SANDISK ANNOUNCES RECORD FOURTH QUARTER REVENUES AND OPERATING INCOME


     o    REVENUE OF $549 MILLION; EPS $0.42
     o    UNITS UP 45% AND MEGABYTES UP 110% SEQUENTIALLY FROM PRIOR QUARTER
     o    PRODUCT GROSS MARGIN INCREASES 3 POINTS TO 32%; OPERATING MARGIN 23%

     SUNNYVALE, CA, January 27, 2005 - SanDisk(R) Corporation (NASDAQ:SNDK), the
world's largest supplier of flash storage card products, today announced results
for the fourth quarter ended January 2, 2005. Total fourth quarter revenues
increased 41% on a year-over-year basis to $549 million and increased 35%
compared to the third quarter of 2004. Fourth quarter net income, which
reflected a 37% tax rate, was $78 million compared to $88 million of net income
in the fourth quarter of 2003, which reflected a 20% tax rate, and $54 million
of net income in the third quarter of 2004. Fully diluted earnings per share for
the fourth quarter were $0.42 compared with $0.47 in the fourth quarter of 2003
and $0.29 in the third quarter of 2004.

     Total revenue for fiscal 2004 was $1.8 billion, up 65% from $1.1 billion in
2003. Product revenues were $1.6 billion, up 63% from $1.0 billion in 2003.
License and royalty revenues were $174 million, up 79% from $97 million in 2003.
Net income was $267 million, up 58% from net income of $169 million in 2003. The
provision for income tax was 37% for 2004 compared to 30% in 2003. Fully diluted
earnings per share for fiscal 2004 were $1.44, compared to $1.02 in 2003.

     "SanDisk experienced outstanding results in our fourth quarter due to
strong demand for our products in digital cameras, USB flash drives, mobile
handsets and our new line of flash digital audio players," said SanDisk CEO Eli
Harari. "In the fourth quarter we sold 110% more megabytes than in the prior
quarter by successfully shifting consumer preference to our higher capacity
cards. Higher yields on our 90-nanometer NAND/MLC, and higher unit volumes
allowed us to aggressively reduce our costs and improve operating margins by
almost 3% in the quarter despite a 34% sequential decline in the average price
per megabyte."

     "In 2005 we will continue our focus on three areas. First, driving growth
in our target consumer and handset markets, including the new storage
opportunities in handsets, flash digital audio players, video games, second
generation intelligent flash drives, and crypto-secure cards. Second, building
our brand and expanding our global sales channels beyond 100,000 storefronts.
Third, executing the transition of our captive volume production from
90-nanometer to 70-nanometer NAND/MLC, as well as ramping the new 300-millimeter
flash fab, both currently scheduled to commence in the second half




of 2005. I am optimistic about the rapidly expanding and pervasive use of our
storage technology and products in numerous emerging markets and applications
over the next several years."

FORWARD-LOOKING STATEMENTS
This news release contains certain forward-looking statements, including our
business outlook, expectations for new product introductions, applications,
markets, customers and the transition and augmentation of our captive
manufacturing capacity that are based on our current expectations and involve
numerous risks and uncertainties that may cause these forward-looking statements
to be inaccurate and may significantly and adversely affect our business,
financial condition and results of operations. Risks that may cause these
forward-looking statements to be inaccurate include among others: market demand
for our products may grow more slowly than our expectations or a slower adoption
rate for these products in new markets that we are targeting, slower than
expected expansion of our global sales channels, fluctuations in operating
results, unexpected yield variances and longer than expected low yields and
other possible delays related to our conversion to 70-nanometer NAND flash
technology or the ramp up of the new 300-millimeter flash fabrication facility,
any interruption of or delay in supply from any of the semiconductor
manufacturing facilities that supply products to us, our inability to make
additional planned smaller geometry conversions in a timely manner, future
average selling price erosion that may be more severe than our expectations due
to possible excess industry capacity of flash memory either from existing
suppliers or from new competitors, price increases from non-captive flash memory
sources and third-party subcontractors, higher than expected operating expenses,
higher than anticipated capital, adverse global economic and geo-political
conditions, including adverse currency exchange rates and acts of terror, the
timely development, internal qualification and customer acceptance of new
products that are based on the 90-nanometer and 70-nanometer NAND technologies,
fluctuations in license and royalty revenues, higher than anticipated tax rates,
regulatory duties or fees, business interruption due to earthquakes or other
natural disasters, particularly in areas in the Pacific Rim and Japan where we
manufacture and assemble products, further impairment of our investments in
Tower Semiconductor Ltd. due to any decline in stock valuations, and the other
risks detailed from time-to-time in our Securities and Exchange Commission
filings and reports, including, but not limited to, the Form 10-K for the year
ended December 28, 2003 and our quarterly reports on Form 10-Q. Future results
may differ materially from those previously reported. We do not intend to update
the information contained in this release.
