General Description

The A625308A is a low operating current 262,144-bit

static random access memory organized as 32,768

words by 8 bits and operates on a 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.

Minimum standby power is drawn by this device when

CE is at a high level, independent of the other input

levels.

Data retention is guaranteed at a power supply voltage

as low as 2.0V.
