General Description
The A623308 is a low operating current 65,536-bit static
random access memory organized as 8,192 words by 8
bits and operates on a single 5V power supply.
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.
