Sony is in talks to sell its advanced semiconductor facilities to Toshiba in a move that would represent an effective retreat from high-end semiconductor fabrication.

People familiar with the matter said on Sunday the two companies were discussing the sale of Sony chip fabrication facilities, including production lines for the “Cell” microprocessor used in Sony’s PlayStation 3 video games consoles. The cost to Toshiba of acquiring the facilities is expected to be about Y100bn ($866m).
