GENERAL DESCRIPTION
The LY621024 is a 1,048,576-bit low power CMOS
static random access memory organized as 131,072
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 LY621024 is well designed for very low power
system applications, and particularly well suited for
battery back-up nonvolatile memory application.
The LY621024 operates from a single power
supply of 5V and all inputs and outputs are fully TTL
compatible
