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 (BYTE WRITE)
DESCRIPTION
The MSM511666C/CL is a 65,536-word
¥
16-bit dynamic RAM fabricated in Oki's silicon-gate CMOS
technology. The MSM511666C/CL achieves high integration, high-speed operation, and low-power
consumption because Oki manufactures the device in a quadruple-layer polysilicon/single-layer
metal CMOS process. The MSM511666C/CL is available in a 40-pin plastic SOJ or 44/40-pin plastic
TSOP. The MSM511666CL (the low-power version) is specially designed for lower-power applications.
FEATURES
