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.
