16-Bit DYNAMIC RAM : FAST PAGE MODE TYPE
DESCRIPTION
The MSM51V18160D/DSL is a 1,048,576-word
¥
16-bit dynamic RAM fabricated in Oki's silicon-
gate CMOS technology. The MSM51V18160D/DSL 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 MSM51V18160D/DSL is available in a 42-pin plastic SOJ or
50/44-pin plastic TSOP. The MSM51V18160DSL (the self-refresh version) is specially designed for
lower-power applications.
