DESCRIPTION
TheISSIIS62C1024AL/IS65C1024ALisalowpower,131,072-
word by 8-bit CMOS static RAM. It is fabricated using high-
performance CMOS technology. This highly reliable pro-
cess coupled with innovative circuit design techniques,
yields higher performance and low power consumption
devices.
When CE1 is HIGH or CE2 is LOW (deselected), the device
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, CE1 and CE2. The active LOW Write Enable
(WE) controls both writing and reading of the memory.
