Product Description
The Serial Quad I/O™ (SQI™) family of flash-memory devices features a 4-bit, multiplexed I/O interface that allows for low-power, high-performance operation in a low pin-count package. System designs using SQI flash devices occupy less board space and ultimately lower system costs.
All members of the 26 Series, SQI family are manufactured with SST proprietary, high-performance CMOS SuperFlash® technology. The split-gate cell design and thick-oxide tunneling injector attain better reliability and manufacturability compared with alternate approaches.
