TOKYO, Aug. 29, 2002 -- M-Systems (Nasdaq: FLSH) and Toshiba Corporation (OTC: TOSBF) (JP: 6502) today announced that they have extended their collaboration in the development, marketing and supply of new products based on Toshiba's latest NAND technologies and M-Systems' DiskOnChip technology. The agreement also provides M-Systems with guaranteed fab capacity.

Also today, the two companies unveiled the advance achieved through their collaboration, the DiskOnChip Millennium Plus 16MB. Both M-Systems and Toshiba will market this jointly developed DiskOnChip.

"Our long lasting relationship with Toshiba and the combination of our technologies has resulted in great success for our companies," said Dov Moran, president and CEO of M-Systems. "Our latest collaboration will satisfy the new market needs that we have identified in mobile, set-top box and other markets. We are very happy to deepen our relationship with Toshiba, the leader and original inventor of NAND Flash."

"M-Systems' DiskOnChip technology enables the effective utilization of Toshiba's NAND flash technology and offers an innovative solution for local storage in set-top boxes, PDAs and smart phones," said Kiyoshi Kobayashi, senior manager of Flash Business Strategy Development of Toshiba. "The unique features of DiskOnChip contributed to strengthen our NAND flash memory offering, and will create the new market arena. Toshiba is very excited to offer its customers DiskOnChip as the solution of choice."

The 16MB DiskOnChip Millennium Plus is the latest flash disk jointly developed by M-Systems and Toshiba. It provides the functionality of a hard drive in a small, solid-state chip and is a complete, monolithic, high-performance local storage solution that offers a better cost structure and ease of integration for devices such as set-top boxes and mobile designs that typically use NOR flash. It also offers additional features such as boot capability, a unique ID, customized protected partitions and a one-time programming (OTP) area for license storage.

M-Systems' TrueFFS technology, supported by leading operating systems such as Microsoft Windows and Symbian OS, contributes to the exceptional performance and reliability of the DiskOnChip Millennium Plus 16MB flash disk.

"M-Systems has combined its experience in system and software with Toshiba, a leading semiconductor memory supplier, to bring a new flash system architecture to market," said Alan Niebel, Web-Feet Research.
