Sony has finalised a deal to purchase the Renesas Electronics semiconductor manufacturing plant in Tsuruoka, Japan, which is responsible for creating the DRAM used by Nintendo in the Wii U.
Sony has reportedly paid about $73 million for the entire facility, which will now become a wholly-owned subsidiary of Sony.
The transfer is expected to be completed by March 31, Sony said, adding that the purchase is intended as a way to strengthen Sony's imaging business.
"As part of this strategy, Sony has been exploring opportunities to increase its production capacity for image sensors, a key component used in mobile products such as smartphones and tablets, for which increasing demand is anticipated."
Neither the press release nor Nintendo itself have addressed how and if this will impact the manufacturing of the Wii U.
