LY6225616
Rev. 1.5
256K X 16 BIT LOW POWER CMOS SRAM
GENERAL DESCRIPTION
The LY6225616 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 LY6225616 is well designed for low power
application, and particularly well suited for battery
back-up nonvolatile memory application.
The LY6225616 operates from a single power
supply of 4.5V ~ 5.5V and all inputs and outputs are
fully TTL compatible
