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,
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 “L” version provides a battery backup/low
voltage data retention mode, offering 2mW maximum power
dissipation at 2 volts. All devices operate from a single +5V
power supply and all inputs and outputs are fully TTL
compatible.
