8K X 8 BIT LOW POWER CMOS SRAM
GENERAL DESCRIPTION
The AS6C6264 is a 65,536-bit low power CMOS
static random access memory organized as 8,192
words by 8 bits. It is fabricated using very high
performance, high reliability CMOS technology. Its
standby current is stable within the range of
operating temperature.
The AS6C6264 is well designed for low power
application, and particularly well suited for battery
back-up nonvolatile memory application.
The AS6C6264 operates with wide range power
supply.
