LY61L1024
Rev. 2.7
128K X 8 BIT HIGH SPEED CMOS SRAM
GENERAL DESCRIPTION
The LY61L1024 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 LY61L1024 is well designed for very high speed
system applications, and particularly well suited for
battery back-up nonvolatile memory application.
The LY61L1024 operates from a single power
supply of 3.3V and all inputs and outputs are fully
TTL compatible
FEATURES
Fast access time : 10/12/15/18ns
Low power consumption:
Operating current : 75/70/65/55mA (TYP.)
Standby current : 0.6mA (TYP.)
1μA (TYP.) LL -version
Single 3.3V power supply
All inputs and outputs TTL compatible
Fully static operation
Tri-state output
Data retention voltage : 2.0V (MIN.)
