    SUNNYVALE, Calif., Jan. 31 /PRNewswire-FirstCall/ -- SST (Silicon Storage
 Technology, Inc., (Nasdaq:   SSTI)), a leader in flash memory technology, and
 Nanotech Corp., an emerging semiconductor foundry located in Changzhou, China,
 today announced the companies have entered into a multi-faceted investment,
 technology licensing and foundry relationship.  Under terms of the agreement,
 Nanotech, will license SST's 0.25micron self-aligned SuperFlash technology,
 thus providing Nanotech's foundry customers, who are developing programmable
 logic and embedded flash memory products, access to SST's high-performance
 flash memory technology.  Additionally, Nanotech's fabrication facility in the
 Changzhou National Hi-Tech District of the People's Republic of China (PRC)
 will serve as a foundry for SST, manufacturing SST's
     SuperFlash-based products at 0.25 micron process geometry.  This
 relationship significantly increases SST's access to low cost manufacturing
 capacity, enabling the company to continue its dominance in the low-density
 flash market.
     "Along with Shanghai, where we have foundry and technology licensing
 partnerships with Grace Semiconductor, Hua Hong NEC and TSMC, Changzhou is
 emerging as a critical center for microelectronics in China," said Bing Yeh,
 president and CEO of SST.  "We have received strong interest for our
 SuperFlash technology from fabless semiconductor suppliers and system
 designers throughout China, and this new relationship with Nanotech will help
 broaden the availability of our embedded flash memory to meet growing demand."
     As part of the agreement, SST, through its subsidiary SST International,
 has purchased Series B preferred shares of Nanotech Corporation, incorporated
 in Cayman Islands.  Proceeds from the Series B and a new round of Series C
 financing are expected to be used to build a new fabrication facility in
 Changzhou, Jiangsu Province, China.
     "SST's SuperFlash technology represents the gold standard in embedded
 flash memory and we are pleased to be able to provide this industry-leading
 technology to our customers," said James Koo, CEO of Nanotech.  "We thank SST
 for its participation in our Series B funding and look forward to working with
 the company for years to come as we serve the global market with a
 cost-optimized, technically robust foundry facility."
     SST was among the first U.S.-based flash memory companies to implement a
 strategy addressing China's rapidly growing semiconductor industry, and was
 the first embedded flash provider to serve the Chinese design community.  SST
 established its wholly owned subsidiary, SST China, in March 2001 to provide
 embedded flash memory design and manufacturing to Chinese design houses, as
 well as to develop and sell flash memory, flash/RAM ComboMemory and embedded
 controller products in the Chinese marketplace.
     Nanotech is an emerging semiconductor foundry with an innovative
 technology that will provide its customers with superior quality, cost and
 time to market.
