DESCRIPTION
The MSM51257CLL is a 32,768-word by 8-bit CMOS static RAM featuring a 5 V power supply
operation and direct TTL input/output compatibility. Since the circuitry is completely static,
external clock and refreshing operations are unnecessary, making this device very easy to use.
The MSM51257CLL, which uses NMOS cells and CMOS peripherals, can be used in high-speed
operation at 55 ns access time and in the very low current consumption of a standby current max.

m
A when there is no chip selection. The MSM51257CLL's ability to hold the memory contents
at 2 V provides a battery back-up. Since the MSM51257CLL is provided with the
CS
and
OE
signals, it can connect with outputs of other chips in a wired OR technique, which provides easy
memory expansion and bus line control.
