TOKYO: Sony said on Wednesday it will sell its microchip production facilities in western Japan to Toshiba for 90 billion yen ($835 million), in their latest move to focus on their core businesses.

The equipment will be used by their semiconductor joint venture that will make high-performance Cell chips and RSX graphic chips, both used in Sony’s PlayStation 3 game console, as well as other microchips that go into Toshiba products. The venture will be established on April 1.

Sony, which is focusing on image sensor chips for digital cameras and pulling away from heavy investments for cutting-edge chip production equipment, said in October it would sell production facilities for making key microchips used in the PS3 to Toshiba, but the price has been unavailable.

The announcement on the selling price comes on the heels of Toshiba’s decision to abandon its high-definition DVD format. Toshiba twinned the HD DVD exit with an announcement that it and SanDisk would spend $16 billion on two new flash memory plants.
