DESCRIPTION
The
speed, 4,194,304-bit static RAMs organized as 524,288
words by 8 bits. They are fabricated using
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.
The IS61C5128AL/AS and IS64C5128AL/AS are packaged
in the JEDEC standard 36-pin SOJ (400-mil), 32-pin sTSOP-
I, 32-pin SOP, 44-pin TSOP-II and 32-pin TSOP-II packages
