256K X 8 BIT HIGH SPEED CMOS SRAM
Rev. 1.0
FEATURES
GENERAL DESCRIPTION
The LY61L2568 is a 2,097,152-bit low power CMOS
static random access memory organized as 262,144
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.
Fast access time : 20/25ns
Very low power consumption:
Operating current(Normal version):
110/90mA(TYP.)
Operating current(20/25ns LL version):
40/35mA(TYP.)
Standby current(Normal version):
0.5mA(TYP.)
Standby current(20/25ns LL version):
The LY61L2568 is well designed for very low power
system applications, and particularly well suited for
battery back-up nonvolatile memory application.
