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.
October 1, 2008

Previous version: Dec. 1996
DESCRIPTION
The MSM548512L is fabricated using OKI’s CMOS silicon gate process technology. This process,
coupled with single-transister memory storage cells, permits maximum circuit density, minimum
chip size and high speed.
MSM548512L has Self-refresh mode in addition to Address-refresh mode and Auto-refresh
mode. In the Self-refresh mode the internal refresh timer and address counter refresh the
dynamic memory cells automatically. This series allows low power consumption when using
standby mode with Self-refresh.
The MSM548512L also features a static RAM-like write function that writes the data into the
memory cell at the rising edge of
WE.
