GENERAL DESCRIPTION
The Austin Semiconductor SRAM family employs
high-speed, low-power CMOS designs using a four-transistor
memory cell. Austin Semiconductor 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 offers a reduced power standby mode when
disabled. 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.
