MSM521218
DESCRIPTION
The MSM521218 is a 65,536-word by 18-bit CMOS fast static RAM featuring a single 3.3 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 MSM521218 can be used in the high-speed operation of an access time 20 ns due to adopting a
high-performance CMOS technology. In addition, the MSM521218 is provided with a chip enable
signal (
CE
) suited to the power-down function, an output enable signal (
OE
) suited to the I/O bus
line control, and a byte select signal (
LB
,
UB
) that can independently control the input/output of a
lower byte and an upper byte.
