General Description
LY62256 General Description
The LY62256 is a 262,144-bit low power CMOS static random access memory organized as 32,768 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 LY62256 is well designed for low power application, and particularly well suited for battery back-up nonvolatile memory application.
The LY62256 operates from a single power supply of 5V and all inputs and outputs are fully TTL compatible
