DESCRIPTION
The MSM51V257CLL is a 32,768-word by 8-bit CMOS static RAM featuring 2.7 V to 3.6 V power
supply operation and direct LVTTL input/output compatibility. Since the circuitry is completely
static, external clock and refreshing operations are unnecessary, making this device very easy to
use. The MSM51V257CLL, which uses NMOS cells and CMOS peripherals, can be used in high-
speed operation at 70 ns access time and in the very low current consumption of a standby current
max. 12
m
A when there is no chip selection. The MSM51V257CLL's ability to hold the memory
contents at 2 V provides a battery back-up. Since the MSM51V257CLL 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.
