DESCRIPTION
The
low power, 131,072-word by 8-bit CMOS static RAMs. They
are fabricated using ISSI 's high-performance CMOS
technology. This highly reliable process coupled with innovative
circuit design techniques, yields higher performance and low
power consumption devices.
When
assumes a standby mode at which the power dissipation can
be reduced by using CMOS input levels.
Easy memory expansion is provided by using two Chip Enable
inputs,
controls both writing and reading of the memory.
The IS61C1024 and IS61C1024L are available in 32-pin
