New Generation Flash Memory Technology Combines Large Capacities and High
Performance For The Enjoyment of Digital Music, Photos, Video And More

LAS VEGAS, NV, Jan. 9, 2003 - SanDisk Corporation (NASDAQ: SNDK)
today introduced the SanDisk Memory Stick® PRO(tm), a new Memory Stick form
that incorporates a variety of advanced capabilities to enable Memory Stick
PRO-optimized devices to capture and play back DVD-quality video in real
time as well as store CD-quality music, high resolution digital images and
other applications that require high performance and large capacities. The
new format, which was jointly developed by Sony and SanDisk, includes
additional features to secure personal content and data loss prevention in
the event of accidental removal of the card during file recording.

Memory Stick PRO cards initially will feature capacities up to one gigabyte
(GB). They will be identified by a unique metallic gold color but are
otherwise identical in physical size and shape to the current generation of
purple Memory Stick cards.

"SanDisk has invested its expertise and intellectual property in its
partnership with Sony to make the Memory Stick PRO a reality," said Nelson
Chan, senior vice president and general manager of SanDisk's Retail Business
Unit. "We believe that the key features of the Memory Stick Pro card-high
performance, large capacities and advanced security features-will
significantly enhance the consumers' usage experience for storing their
music, photos and videos on their optimized devices."

In addition, Memory Stick PRO cards feature advanced capabilities that will,
when combined with devices that are optimized for the Memory Stick PRO
format, ensure greater reliability by preventing data loss due to sudden
power loss or accidental removal of media while recording or transferring
files. Memory Stick PRO media can be safely removed during a file transfer
process without the risk of damaging the file structure on the media.

For security, consumers can protect their personal data on the Memory Stick
PRO cards with a file protection mechanism that prevents unauthorized access
to the files in the event the card is lost or stolen. For commercial content
providers, the new format includes the MagicGate(tm) copyright technology,
which provides secure protection of commercial and copyrighted content, such
as digital music and, in the future, video and games.

The SanDisk Memory Stick PRO cards will be available in 256 megabytes (MB),
512MB and 1 gigabyte (GB) capacities. They are expected to be available in
April at many of the 50,000 retail stores world wide where SanDisk-branded
products are sold at prices ranging from $189 to $879.
