General Description
The A616316 is a high speed 1,048,576-bit static random
access memory organized as 65,536 words by 16 bits
and operates on supply voltage 5V. It is built using
AMIC's high performance CMOS process.
Inputs and three-state outputs are TTL compatible and
allow for direct interfacing with common system bus
structures.
The chip enable input is provided for POWER-DOWN, to
disable the device. Two byte enable inputs and an output
enable input are included for easy interfacing.
Data retention is guaranteed at a power supply voltage
as low as 3V.
