LY616416
Rev. 1.2
5V 64K X 16 BIT HIGH SPEED CMOS SRAM
GENERAL DESCRIPTION
The LY616416 is a 1,048,576-bit low power CMOS
static random access memory organized as 65,536
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 LY616416 is well designed for low power
application, and particularly well suited for battery
back-up nonvolatile memory application.
The LY616416 operates from a single power
supply of 5V and all inputs and outputs are fully TTL
compatible
FEATURES
Fast access time : 15/20ns
Low power consumption:
Operating current : 140/110mA(MAX.)
Standby current :
