64K x 16 HIGH-SPEED CMOS STATIC RAM

WITH 3.3V SUPPLY

DESCRIPTION

The

RAM organized as 65,536 words by 16 bits. It is fabricated

using

reliable process coupled with innovative circuit design

techniques, yields access times as fast as 8 ns with low power

consumption.

When

CE is HIGH (deselected), the device assumes a standby

mode at which the power dissipation can be reduced down with

CMOS input levels.

Easy memory expansion is provided by using Chip Enable and

Output Enable inputs,

CE and OE. The active LOW Write

Enable (

WE) controls both writing and reading of the memory.

A data byte allows Upper Byte (

UB) and Lower Byte (LB)

access.

The IC61LV6416 is packaged in the JEDEC standard 44-pin

400mil SOJ, 44-pin 400mil TSOP-2, and 48-pin 6*8mm TF-

BGA.
