GENERAL DESCRIPTION
The LY6210248 is a 8,388,608-bit low power CMOS
static random access memory organized as
1,048,576 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 LY6210248 is well designed for very low power
system applications, and particularly well suited for
battery back-up nonvolatile memory application.
The LY6210248 operates from a single power
supply of 4.5V ~ 5.5V and all inputs and outputs are
fully TTL compatible
