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\) 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 accomplished
when WE\ remains HIGH and CE\ and OE\ go LOW. The
device offers a reduced power standby mode when disabled.
This allows system designs to achieve low standby power
requirements.
The 鈥淟鈥?version provides an approximate 50 percent
reduction in CMOS standby current (I
SBC2
) over the standard
version.
All devices operate from a single +5V power supply
and all inputs and outputs are fully TTL compatible.
