9/21/2004 - SST (Silicon Storage Technology, Inc., NASDAQ: SSTI), a leader in flash memory technology, further solidified its position as the supplier of choice to the wireless industry by expanding its offering of 1.8-volt NOR flash memory devices. Addressing the need for high-performance, low-power and small-footprint memory devices, the new 8-Mbit SST39WF800A is offered in several package options, including SST’s tiny Micro-Package, the industry’s smallest standard flash memory package, and boasts sector- and chip-erase speeds that are hundreds of times faster than alternative solutions. The combination of high performance and small size makes the SST39WF800A ideal for power- and space-constrained applications such as MP3 players, Bluetooth modules and GPS devices. In fact, to date, SST’s 1.8-volt flash memory devices have been used by a number of the world’s leading Bluetooth chipset and module manufacturers.
The SST39WF800A is the latest addition to SST’s successful Multi-Purpose Flash (MPF) product family. The device is pin compatible with SST’s 4-Mbit 1.8-volt device as well as the company’s 3-volt 2-, 4- and 8-Mbit MPF devices, thus providing an easy migration path for customers looking to lower power consumption or increase memory density in their designs.
Because the SST39WF800A is based on SST’s SuperFlash technology, the device features several advantages over alternative solutions. The small sector size of the SST39WF800A allows system designers to easily partition the data and program code into small, uniform 2 KWord segments – 16 times smaller than competitors – resulting in more efficient firmware design, better system performance, reduced power usage and even lower cost due to the firmware size being compacted into a smaller memory density. The SST39WF800A achieves chip erase times of no more than 200 milliseconds, which is 280 times faster than the typical 14 second chip erase times of alternative 1.8-volt flash memories. Because of the device’s small sector size, the SST39WF800A features a maximum block erase time of 50 milliseconds, 300 times faster than the 15 second block erase times of alternative solutions. The device’s maximum Word programming time of 40 microseconds is more than five times faster than the 210 microseconds achieved by competitive products.
"Our 1.8-volt product offering gives our customers more options to enhance the functionality of their portable devices without sacrificing battery life or size," said Jason Feinsmith, business director, Standard Memory Product Group at SST. "With the 8-Mbit device, we look forward to expanding on the tremendous success our 1.8-volt products have already experienced in Bluetooth and other wireless markets."
Pricing and Availability
The SST39WF800A is available now. It is priced at $1.90 each in 10K unit quantities. In addition to several package options, the SST39WF800A is available in die and wafer form.
About SuperFlash Technology
SST's SuperFlash technology is a NOR type, split-gate cell architecture which uses a reliable thick-oxide process with fewer manufacturing steps resulting in a low-cost, nonvolatile emory solution with excellent data retention and higher reliability. The split-gate NOR SuperFlash architecture facilitates a simple and flexible design suitable for high performance, high reliability, small or medium sector size, in- or off-system programming and a variety of densities, all in a single CMOS-compatible technology.
