Toyota supplier Denso is reportedly in talks to acquire shares of chipmaker Rohm in a potential $8.3 billion deal. The acquisition would expand Denso's control over power management chips essential for electric vehicles and data centers.

Rohm, based in Kyoto, is a key player in power chips, critical for efficiently managing electric power in vehicles, electronics, and industrial equipment. This strategic move comes as Japan's chip industry, despite its strengths in certain areas like power chips, faces fragmentation and calls for consolidation.

Shares of Rohm saw a surge in buy orders following the announcement, while Denso's shares experienced a decline.
