LY6212816
Rev. 1.1
128K X 16 BIT LOW POWER CMOS SRAM
GENERAL DESCRIPTION
The LY6212816 is a 2,097,152-bit low power CMOS
static random access memory organized as 131,072
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 LY6212816 is well designed for low power
application, and particularly well suited for battery
back-up nonvolatile memory application.
The LY6212816 operates from a single power
supply of 4.5V ~ 5.5V and all inputs and outputs are
fully TTL compatible
FEATURES
