The MSM52258 is a 32,768-word by 8-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 MSM52258 uses NMOS cells and CMOS peripherals and provides high-speed operation at 15 ns access time. Since the MSM52258 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.
