GENERAL DESCRIPTION
The Micross Components SRAM family employs high-speed,
low-power CMOS designs using a four-transistor memory cell.
Micross Components SRAMs 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 X1 configuration features
separate 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 of-

fers a reduced power standby mode when
disabled. This
allows system designs to achieve low standby power require-
ments.
All devices operate from a single +5V power supply and all
inputs and outputs are fully TTL compatible.
