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.

1-Bit DYNAMIC RAM : STATIC COLUMN MODE TYPE
DESCRIPTION
The MSM514102D/DL is a 4,194,304-word
¥
1-bit dynamic RAM fabricated in Oki's silicon-gate
CMOS technology. The MSM514102D/DL 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 MSM514102D/DL is available in a 26/20-pin plastic SOJ, 20-
pin plastic ZIP, or 26/20-pin plastic TSOP. The MSM514102DL (the low-power version) is specially
designed for lower-power applications.
