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.
