GENERAL DESCRIPTION
The AS6C2008A is a 2,097,152-bit low power CMOS static random access memory organized as 262,144 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 AS6C2008A is well designed for very low power system applications, and particularly well suited for battery back-up nonvolatile memory application. The AS6C2008A operates from a single power supply of 2.7V ~ 5.5V and all outputs are fully TTL compatible
