MSM51V18165B/BSL
1,048,576-Word ¥ 16-Bit DYNAMIC RAM : FAST PAGE MODE TYPE WITH EDO
DESCRIPTION
The MSM51V18165B/BSL is a 1,048,576-word ¥ 16-bit dynamic RAM fabricated in Oki's silicon-gate
CMOS technology. The MSM51V18165B/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 MSM51V18165B/BSL is available in a 42-pin plastic SOJ or
50/44-pin plastic TSOP. The MSM51V18165BSL (the self-refresh version) is specially designed for
lower-power applications.
