DiskOnChip devices boost handset storage
A new line of DiskOnChip devices features capacities of 8 and 4Gbit (1Gbyte and 512Mbyte), targeting high-end music and video centric handsets.
A new line of DiskOnChip devices features capacities of 8 and 4Gbit (1Gbyte and 512Mbyte), targeting high-end music and video centric handsets Featuring M-Systems' advanced x2 technology that enables the implementation of multi-level cell (MLC) NAND Flash silicon, the DiskOnChip H-series of products is based on 90nm process MLC large block NAND Flash, with products based on 70nm process planned for the end of 2005

Check Point Software Technologies is using M-Systems' solid state drives in continuous virtual private network system integration projects.
DiskOnChip H1, the first release of this new product line, provides a highly reliable and robust embedded memory solution to answer the growing demand for drastically increased storage capacity within the mobile industry's latest multimedia devices.
The unique combination of MLC NAND Flash, x2 technology and M-Systems' TrueFFS Flash file system, ideal for the management of MP3 and other multimedia files, results in a low-cost, minimally sized Flash disk that achieves extremely high levels of reliability, enhanced performance and very high capacity within a single chip.
"With 3G networks finally in service, we see an increase in streaming video and music content delivery services, such as iTunes, introduced in the handset arena", said David Tolub, General Manager of M-Systems' Mobile Division.

SIM cards magnify handset storage
M-Systems has announced the availability of high-capacity mSIM MegaSIM cards through its Microelectronica subsidiary.
"For network operators to capitalise on this opportunity, they'll require handsets with much higher storage capacities than ever before".
"The DiskOnChip H-series addresses this demand and, because it is an embedded solution, it provides the ability to control the redistribution of downloaded content to protect the rights of operators and content owners".
"Some of the handsets on the market offer expandable memory slots, and we're even seeing the integration of hard drives into some fringe mobile handset designs - all in an effort to increase storage capacity for a variety of multimedia files including music, photos and video", said Allen Nogee, Principal Analyst, InStat-MDR.
"Based on solid state MLC NAND Flash technology, DiskOnChip H-series delivers the capacity and performance required for multimedia with a fraction of the power and size penalty of micro drives".
"In addition, with no moving parts, it can easily sustain falls and other shocks that handsets often experience and that would cause conventional spinning media to fail".
Like other DiskOnChip products from M-Systems, the DiskOnChip H-series features a legacy NOR-compatible interface, allowing it to be used with any mobile chipset.
In comparison, even the most advanced mobile chipsets and software drivers do not yet support MLC NAND technology as well as large block NAND technology, restricting OEMs to more costly alternatives, such as conventional, small block binary NAND, removable media and hard drives.
Further cost benefits are derived from the efficient architecture of DiskOnChip H1, which includes a boot block that can replace expensive NOR Flash alternatives.
Furthermore, compared with micro drives, DiskOnChip consumes up to 90% less power, is significantly more rugged and, at 12 x 18 x 1.4mm, is, at most, 12% of the size.
The 4Gbit (512Mbyte) DiskOnChip H1 based on 90nm process MLC NAND will be available Q1 2005 with the 8Gbit (1Gbyte) model to follow in Q2 2005.
DiskOnChip H-series products based on 70nm process MLC NAND are currently planned for Q4 2005.
