GENERAL DESCRIPTION
The Austin Semiconductor SRAM family employs
high-speed, low power CMOS designs using a four-transistor
memory cell. These SRAMs are fabricated using double-layer
metal, double-layer polysilicon technology.
For flexibility in high-speed memory applications, Aus-
tin Semiconductor offers chip enable (CE\) and output enable
(OE\) capability. These enhancements can place the outputs in
High-Z for additional flexibility in system design.
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\ and OE\ go LOW.
The device offers a reduced power standby mode when dis-
abled. This allows system designs to achieve low standby
power requirements.
All devices operate from a single +5V power supply
and all inputs and outputs are fully TTL compatible.
