SST Unveils World's First Low-Voltage, High-Speed Quad I/O Serial Flash Memory

New 26WF Series SQI Flash Devices Achieve Fastest Random Access Performance of
Any Quad-bit Serial Memory

SUNNYVALE, Calif., Nov. 2 /PRNewswire-FirstCall/ -- SST (Silicon Storage
Technology, Inc.) (Nasdaq: SSTI), a leader in flash memory technology, today
announced the industry's first 1.8V, high-speed quad-bit serial flash memory.
Featuring an 80 MHz operating frequency and a specialized instruction set, the
new 26WF Series Serial Quad I/O (SQI) family of 4-bit multiplexed I/O serial
interface devices enables execute-in-place (XIP) capability, allowing programs
to be stored and executed directly from the flash memory without the need for
code shadowing on an SRAM. The 26WF Series, the first high-performance 1.8V
quad I/O serial flash product, marries the performance typically associated
with parallel flash memory, with the low pin count and space savings of serial
flash memory, plus reduced power. This combination of high performance and low
power consumption is ideal for mobile handsets, Bluetooth headsets, GPS
devices and other small form factor, portable electronics.

Today's announcement builds on the success of SST's 3.0V SQI flash products,
the 26VF Series, which in April of this year won an Innovation of the Year
Award from EDN Magazine. Both 26 Series devices from SST feature a novel read
memory indexing feature that enables the devices to achieve the industry's
fastest random access performance of any quad-bit serial memory. Read memory
indexing allows the system to jump from one address to another within a
256-Byte page, within a 64-KByte block or from one block to another using
indirect addressing. This results in a significant reduction in the number of
clock cycles and dramatically accelerates data access.

With sustained burst data rates of up to 320 Mbit/sec., the 26WF Series
devices provide serial flash performance exceeding that of typical parallel
flash memory. To provide additional system speed and performance while
reducing access time, the 26WF devices support 8-, 16-, 32- and 64-Byte burst
mode operation with wrap around. This feature allows designers to execute code
in burst snippets for RAM-less applications or fill cache line buffers for
applications where the system architecture uses pipelining to maximize bus
bandwidth.

The 26WF Series SQI devices offer memory write performance enhancements to
improve overall device performance, including flexible erase capability to
erase small block sectors on the chip in as little as 25 ms or the entire
flash memory chip in 50 ms. The devices also support write suspend and resume
operation so a program can suspend a write operation to access another block
of memory within the same clock cycle.

"The mobile phone industry, in particular, has been yearning for a serial
memory solution with high performance and extremely low power consumption and
we are proud to be the first in the industry to achieve this highly
challenging accomplishment," said Douglas Lee, vice president, Memory
Products, SST. "In addition to performance and power consumption advantages,
our new 26WF Series offers designers of ultra low-cost mobile handsets with a
low pin count, quad I/O protocol serial flash memory that is straightforward
and easy to integrate, enabling continued system cost reduction. Today's
announcement solidifies our leadership in low-voltage, high-speed serial flash
memory and underscores our commitment to providing customers with the
solutions they need to achieve their design goals."

The 26WF Series SQI devices are built upon SST's native 1.8V SuperFlash memory
cell, providing inherently higher performance when compared to alternative
quad-bit devices that would require power-hungry charge pump circuitry for
1.8V operation, resulting in performance limitations. The 26WF Series products
offer superior reliability of 100,000 cycles endurance (typical) and greater
than 100 years data retention. The active read current of the devices is only
15 milliamperes (typical at 80 MHz) and standby current is a mere 10
microamperes (typical).

To ensure code security, all 26WF Series devices support software write
protection for individual blocks, the upper and lower 64-KBytes of memory are
partitioned into smaller 8-KByte sectors that can both read- and write-lock.
In addition, the devices include a one-time programmable secure ID area,
consisting of a 64-bit factory programmed unique ID and a 192-bit user
programmable block.

All 26WF Series SQI devices are available in both commercial and industrial
temperature ranges, and are offered in an 8-contact WSON (6mm x 5mm) or 8-lead
SOIC (200 mil) package. In addition to the 1.8V 26WF Series, SST offers 3.0V
SQI devices in 16 Mbit and 32Mbit densities.

Pricing and Availability
The first product in the 26WF Series SQI family is the 32 Mbit SST26WF032.
Samples of the product are available now to select customers, with volume
production scheduled for Q1 2010. Pricing for the SST26WF032 device is $3.20
each in 10K unit quantities. Additional products in the series will be
announced at a later date.
