DESCRIPTION

The MSM51V16800D/DSL is a 2,097,152-word ¥ 8-bit dynamic RAM fabricated in Oki's silicon-gate

CMOS technology. The MSM51V16800D/DSL achieves high integration, high-speed operation,

andlow-powerconsumptionbecauseOkimanufacturesthedeviceinaquadruple-layerpolysilicon/

double-layer metal CMOS process. The MSM51V16800D/DSL is available in a 28-pin plastic SOJ or

28-pin plastic TSOP. The MSM51V16800DSL (the self-refresh version) is specially designed for

lower-power applications.
