M-Systems and Toshiba Agree to an Unprecedented Level of Strategic Collaboration in Flash Memory-based Data Storage

29 July, 2003


A Comprehensive Agreement Includes Joint Product Development,
Cross Licensing, Capacity Guarantees,
and Strategic Investment by Toshiba in M-Systems

TOKYO and KFAR SABA, Israel, July 29, 2003 -- M-Systems (Nasdaq: FLSH), a leader in flash-based data storage, and Toshiba Corporation (OTC: TOSBF) (JP:6502), a leader in the development and manufacture of NAND flash, today announced that they have raised their partnership to a new level, with a comprehensive agreement intended to combine the two companies' technology leadership in developing new NAND flash-based data storage products. The agreement includes joint development of next-generation products as well as cross licensing of intellectual property (IP), guarantees for M-Systems regarding capacity of the NAND flash, and -- for the first time -- a strategic investment by Toshiba in M-Systems.

"Toshiba and M-Systems have worked closely together for many years and this agreement complements the cooperation we have both enjoyed," said Masashi Muromachi, vice president of Toshiba Corporation Semiconductor Company. "DiskOnChip has gained acceptance as the preferred data storage solution for high-end mobile handsets. Utilizing its strong technology and IP, M-Systems has also propelled DiskOnKey to be the world's leading product in the fast growing USB drive portable storage market. This Agreement gives Toshiba important IP that allows us to further expand NAND flash memory applications."

NAND flash is gaining ever-wider awareness and acceptance as the best non-volatile memory solution for a wide variety of applications from cell phones, embedded systems, and consumer devices to mission critical applications. M-Systems and Toshiba have long been strong proponents of using NAND flash for data storage due both to its cost structure and to its high density capabilities. M-Systems' world-class technologies and expertise enabled NAND flash to become an ideal platform for data storage by making the flash more reliable, higher performing and easier to integrate, all while maintaining a competitive cost structure.

"Throughout the many years that we have worked together, Toshiba has proved its leading edge technology and has learned to appreciate our knowledge and contribution to the expansion of the flash data storage market," said Dov Moran, president and CEO of M-Systems. "We are very proud to expand our partnership with Toshiba while securing a steady supply of NAND flash. We are also greatly improving our ability to offer new, even more cost-competitive solutions to the market. This is yet another important leap forward for M-Systems."
