Dear customers,
About the change in the name such as "Oki Electric Industry Co. Ltd." and
"OKI" in documents to OKI Semiconductor Co., Ltd.
The semiconductor business of Oki Electric Industry Co., Ltd. was succeeded to OKI
Semiconductor Co., Ltd. on October 1, 2008.
Therefore, please accept that although
the terms and marks of "Oki Electric Industry Co., Ltd.", “Oki Electric”, and "OKI"
remain in the documents, they all have been changed to "OKI Semiconductor Co., Ltd.".
It is a change of the company name, the company trademark, and the logo, etc. , and
NOT a content change in documents.

16-Bit DYNAMIC RAM : FAST PAGE MODE TYPE WITH EDO
DESCRIPTION
The MSM51V16165D/DSL is a 1,048,576-word
¥
16-bit dynamic RAM fabricated in Oki's silicon-
gate CMOS technology. The MSM51V16165D/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 MSM51V16165D/DSL is available in a 42-pin plastic SOJ or
50/44-pin plastic TSOP. The MSM51V16165DSL (the self-refresh version) is specially designed for
lower-power applications.
