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.

MSM51V16165F
DESCRIPTION
FEDD51V16165F-03
Issue Date: Aug. 16, 2002
1,048,576-Word
×
16-Bit DYNAMIC RAM : FAST PAGE MODE TYPE WITH EDO
The MSM51V16165F is a 1,048,576-word
×
16-bit dynamic RAM fabricated in Oki’s silicon-gate
CMOS technology. The MSM51V16165F 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 MSM51V16165F is available in a 50/44-pin plastic
TSOP.
