GENERAL DESCRIPTION
The WS6264 is a high performance, high speed and super low power CMOS Static Random
Access Memory organized as 8,192 words by 8bits and operates from a single 4.5V to 5.5V supply voltage.
Advanced CMOS technology and circuit techniques provide both high speed, super low power features and
maximum access time of 70ns in 5.0V operation. Easy memory expansion is provided by using two chip
enable inputs (/CE1, CE2) and active LOW output enable (/OE).
The WS6264 has an automatic power down feature, reducing the power consumption significantly
when chip is deselected. The WS6264 is available in JEDEC standard 28-pin SOP(300 mil) and PDIP
(600 mil) packages.
