DESCRIPTION The ISSI IS61C5128AL/AS and IS64C5128AL/AS are high-
speed, 4,194,304-bit static RAMs organized as 524,288
words by 8 bits. They are fabricated using ISSI's high-
performance
CMOS technology.This highly reliable process coupled with innovative circuit design techniques, yields access times as fast as 12 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.
