LY61L256
Rev. 1.2
32K X 8 BIT HIGH SPEED CMOS SRAM
GENERAL DESCRIPTION
The LY61L256 is a 262,144-bit high speed CMOS
static random access memory organized as 32,768
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 LY61L256 is well designed for high speed
system application. Easy expansion is provided by
using an active LOW Chip Enable(CE#). The active
LOW Write Enable(WE#) controls both writing and
reading of the memory.
The LY61L256 operates from a single power
supply of 3.3V and all inputs and outputs are fully
TTL compatible
