MSM51V16805B/BSL

DESCRIPTION

The MSM51V16805B/BSL is a 2,097,152-word

¥ 8-bit dynamic RAM fabricated in Oki's silicon-gate

CMOS technology. The MSM51V16805B/BSL achieves high integration, high-speed operation, and

low-power consumption because Oki manufactures the device in a quadruple-layer polysilicon/

double-layer metal CMOS process. The MSM51V16805B/BSL is available in a 28-pin plastic SOJ or

28-pin plastic TSOP. The MSM51V16805BSL (the self-refresh version) is specially designed for

lower-power applications.
