LY611024
Rev. 1.6
128K X 8 BIT HIGH SPEED CMOS SRAM
GENERAL DESCRIPTION
The LY611024 is a 1,048,576-bit low power CMOS
static random access memory organized as 131,072
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 LY611024 is well designed for very high speed
system applications, and particularly well suited for
battery back-up nonvolatile memory application.
The LY611024 operates from a single power
supply of 4.5V ~ 5.5V and all inputs and outputs are
fully TTL compatible
