128K X 8 BIT HIGH SPEED CMOS SRAM
General Description
The A6173081 is a high-speed 1,048,576-bit static random access memory organized as 131,072 words by 8 bits and operates on a 5V power supply. It is built using high performance CMOS process. Inputs and three-state outputs are TTL compatible and allow for direct interfacing with common system bus structures. Minimum standby power is drawn by this device when chip enable is disable, independent of the other input levels. Data retention is guaranteed at a power supply voltage as low as 3V.

Notes: 1. 2. 3. 4.
tAS is measured from the address valid to the beginning of Write. A Write occurs during the overlap (tWP) of a low CE and a low WE . tWR is measured from the earliest of CE or WE going high to the end of the Write cycle If the CE low transition occurs simultaneously with the WE low transition or after the WE transition, outputs remain in a high impedance state. 5. tCW is measured from the later of CE going low to the end of Write. 6. OE is continuously low. ( OE = VIL) 7. Transition is measured 200mV from steady state. This parameter is sampled and not 100% tested.
