GENERAL DESCRIPTION
The LY62102516 is a 16,777,216-bit low power
CMOS static random access memory organized as
1,048,576 words by 16 bits. It is fabricated using
very high performance, high reliability CMOS
technology. Its standby current is stable within the
range of operating temperature.
The LY62102516 is well designed for low power
application, and particularly well suited for battery
back-up nonvolatile memory application.
The LY62102516 operates from a single power
supply of 4.5V ~ 5.5V and all inputs and outputs are
fully TTL compatible
