GENERAL DESCRIPTION

The Austin Semiconductor SRAM family employs

high-speed, low-power CMOS and are fabricated using double-

layer metal, double-layer polysilicon technology.

For flexibility in high-speed memory applications,

Austin Semiconductor offers chip enable (CE\) on all organiza-

tions. This enhancement can place the outputs in High-Z for

additional flexibility in system design. The x4 configuration

features common data input and output.

Writing to these devices is accomplished when write

enable (WE\) and CE\ inputs are both LOW. Reading is accom-

plished when WE\ remains HIGH and CE\ goes LOW. The

device offers a reduced power standby mode when disabled.

This allows system designs to achieve low standby power re-

quirements.

These devices operate from a single +5V power sup-

ply and all inputs and outputs are fully TTL compatible.
