FREMONT, Calif., April 11, 2001 — Lexar Media (NASDAQ: LEXR), a leading designer, developer and marketer of award-winning digital film and connectivity products for the digital photography market, announced today that it is now engaged in litigation with Memorex (Memtek Products, Inc.) over Memorex’s infringement of Lexar Media’s flash memory controller patents. “It is with regret that we take this course of action, but Memorex has retreated from its commitments to sell non-infringing CompactFlashä products,” said Eric Whitaker, Lexar Media’s Vice President of Technology Licensing. “Lexar Media is committed to aggressively protecting its investments in patent and technology development against those who use our inventions. While a number of companies have recently agreed to purchase our controllers to produce CompactFlash cards, there unfortunately remain a number of new entrants in the flash market that do not respect the work that Lexar Media has put into developing these technologies–despite the fact that companies such as Sony and SanDisk have licensed our patents.” Lexar Media added that it believes that customers who buy Memorex’s CompactFlash products or who build devices with flash memory controllers from unlicensed vendors such as Pretec or C-One that use Lexar Media’s patented technology may also be infringing these patents. Lexar Media intends to seek an injunction against Memorex’s further sales of infringing products and damages.  Lexar Media, a pioneering technology company in the flash memory controller market, holds more than 30 patents related to developing and designing a programmable flash memory controller and flash memory cards. Memorex is one of several companies Lexar Media is suing for intellectual property infringement.
