The MSM521004 is a 262,144-word by 4-bit CMOS fast static RAM featuring a single 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 MSM521004 uses NMOS cells and CMOS peripherals and provides high-speed operation at 17 ns access time. In addition, the MSM521004 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.
