PRODUCT FAMILY
The LY625128 is a 4,194,304-bit low power CMOS
static random access memory organized as 524,288
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 LY625128 is well designed for very low power
system applications, and particularly well suited for
battery back-up nonvolatile memory application.
The LY625128 operates from a single power
supply of 4.5V ~ 5.5V and all inputs and outputs are
fully TTL compatible
