LY61L25616
Rev. 2.1
256K X 16 BIT HIGH SPEED CMOS SRAM
GENERAL DESCRIPTION
The LY61L25616 is a 4,194,304-bit low power
CMOS static random access memory organized as
262,144 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 LY61L25616 is well designed for low power
application, and particularly well suited for battery
back-up nonvolatile memory application.
The LY61L25616 operates from a single power
supply of 3.3V and all inputs and outputs are fully
TTL compatible
