SST (Silicon Storage Technology, Inc.), one of the leaders in the Flash Memory technology announced worlds first 1.8V, high-speed
quad-bit serial flash memory.
The memory includes an 80 MHz operating frequency, and 26 WF Series Serial Quad I/O (SQI) family of 4-bit multiplexed I/O serial interface
devices, to activate XIP (execute in place capability).
Once XIP is enabled, programs do not require code shadowing on SRAM. They can be executed directly from the flash memory. Besides, the memory functions efficiently even at a low power consumption.
"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 26 WF Series SQI devices are based on a number of advanced features. Small block sectors on the chip may be erased within 25 ms whereas it takes only 50 ms to erase the entire chip. The write suspend and resume operations make memory manipulation remarkably easy and effective. 26WF Series devices provide software write protection to ensure code security. Besides, the secure ID area can be programmed only once.
