MSM521218 General 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.
