Sony not selling chip operations unit

Japan's Sony is looking at ways to improve its chip operations but has reached no decision on whether to sell it, denying Japanese media reports that it has struck a deal with Toshiba, an Associated Press report said.

Toshiba spokesman Keisuke Omori also said no deal has been decided, according to the Associated Press report.

Japan's top business daily, The Nikkei, reported that Sony has decided to sell its advanced computer chip production operations to Toshiba, which partnered with Sony and IBM in developing the 'Cell' microprocessor.

The speculation about the future of Sony's chip operations comes amid a restructuring at Sony and intensifying competition among the world's computer chip makers, the report said.

Sony has been saying for months it's exploring ways to streamline its chip business as it focuses on home entertainment devices. 'But nothing concrete has been decided,' Sony spokesman Tomio Takizawa, quoted by the Associated Press report, said.
