GENERAL DESCRIPTION
The LY62102616 is a 16,777,216-bit low power
CMOS static random access memory organized as
1,048,576 words by 16 bits or 2,097,152 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 LY62102616 is well designed for low power
application, and particularly well suited for battery
back-up nonvolatile memory application.
The LY62102616 operates from a single power
supply of 4.5V ~ 5.5V and all inputs and outputs are
fully TTL compatible
