MSM51V17805B/BSL
2,097,152-Word ¥ 8-Bit DYNAMIC RAM : FAST PAGE MODE TYPE WITH EDO
DESCRIPTION
The MSM51V17805B/BSL is a 2,097,152-word ¥ 8-bit dynamic RAM fabricated in Oki's silicon-gate
CMOS technology. The MSM51V17805B/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 MSM51V17805B/BSL is available in a 28-pin plastic SOJ or
28-pin plastic TSOP. The MSM51V17805BSL (the self-refresh version) is specially designed for
lower-power applications.
