General Description

The A627308 is a low operating current 1048,576-bit

static random access memory organized as 131,072

words by 8 bits and operates on a power supply voltage

from 4.5V to 5.5V.

Inputs and three-state outputs are TTL compatible and

allow for direct interfacing with common system bus

structures.

Two chip enable inputs are provided for power down and

a write enable and an output enable input are included

for easy interfacing.

Data retention is guaranteed at a power supply voltage

as low as 2V.
