GENERAL DESCRIPTION
Austin Semiconductor SRAMs are fabricated using double-layer metal, double-layer polysilicon technology. 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.
