Announcing x4(TM) Technology Breakthrough, msystems(TM) Takes the NAND Industry to the Next Level.

KFAR SABA, Israel -- Ground-breaking 4-bit per cell NAND flash technology is designed to revolutionize NAND flash manufacturing economics, increase fab profitability and fuel new generations of multimedia-rich, consumer electronics devices

msystems(TM) (Nasdaq:FLSH), a leader in smart personal storage, today announced x4(TM) technology, a technological breakthrough designed to revolutionize NAND flash manufacturing economics, increase fab profitability with no changes to manufacturing processes, and fuel new generations of multimedia-rich, consumer electronics devices.

As a proprietary msystems' technology encompassing unparalleled flash management and control algorithms, x4 technology is designed to enable utilization of 4-bit/cell NAND flash, previously considered to be a practical and physical impossibility. x4 NAND components, likely to be mass produced during 2007, are to be comprised of the first-ever 4-bit/cell NAND flash media and an indispensable x4 technology controller. Thanks to msystems' technological breakthrough, NAND flash manufacturers are expected to realize over 30% cost savings in comparison with the most advanced 2-bit/cell multi-level cell (MLC) NAND flash wafers manufactured to date through equivalent lithography. This is accomplished by doubling bit density in comparison with such MLC NAND flash, and quadrupling it when compared with single-level cell (SLC) NAND flash. Furthermore, as msystems' x4 technology requires no changes to manufacturing processes, it stands to increase fab profitability.

"This is a phenomenal day for NAND flash manufacturers and the consumer electronics market, as well as for msystems," said Dov Moran, president and CEO of msystems. "x4 technology is msystems' highest peak in a sixteen-year trail of continuous innovation and systems-level expertise as well as the culmination of five years of dedicated research and development efforts. Based on msystems' robust flash management patent portfolio, x4 technology represents a quantum leap forward for the flash industry, underlining our ongoing commitment to making personal storage smarter. Judging by the undisputed success of 2-bit/cell MLC NAND flash technology and the significant cost savings x4 technology is designed to deliver to NAND flash manufacturers, we believe x4 NAND components are set to further push flash memory from prevalent to pervasive, ushering in new generations of affordable, multimedia-rich, personal storage for consumer electronics devices."

With a decrease in price per gigabyte (GB) of more than 80 percent over the past three years, NAND flash storage is the memory medium of choice for a plethora of devices in the consumer electronics space. msystems' x4 NAND components are expected to target consumer electronics devices, such as digital audio (MP3) players, consumer solid state drives (SSDs), portable media players, digital video cameras, GPS devices, multimedia and music handsets, memory cards and USB flash drives.

Driven by the widespread availability of personal storage devices, the demand for NAND flash memory is expected to grow by leaps and bounds. In recent research, Gartner forecast that the NAND flash market would grow from $11.96 billion in 2005 to $24.70 billion in 2010. Decreasing prices and surging demand have pushed manufacturers to look for new ways to maximize bit density per wafer, in the hope of driving fab profitability and return on investment. msystems' x4 technology, through its ability to transparently quadruple the density of SLC NAND flash wafers, has been developed to provide this sought-after advantage.

"The NAND flash market is experiencing phenomenal growth fueled by the digital revolution. Building new manufacturing fabs to satisfy tremendous demand requires huge investments, and such efforts may not be recognized in a fiercely competitive environment," said Joseph Unsworth, principal research analyst, Gartner. "Technology developments that leverage existing NAND manufacturing processes can be critical in helping manufacturers achieve significant cost savings without the burden of major capital expenditures, thereby enabling higher profitability."

A proprietary technology, x4 is well rooted in msystems' vast flash management expertise, such as its renowned TrueFFS(R) technology, its system-solution approach and robust intellectual property portfolio. Several x4 technology partnerships are currently being evaluated by msystems, and are likely to lead to mass production of x4 NAND components during 2007.
