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
organizations. 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
accomplished 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 requirements.
These devices operate from a single +5V power
supply and all inputs and outputs are fully TTL compatible.
