Semiconductor manufacturer Renesas Electronics has announced that it is to close four semiconductor plants in Japan within 2-3 years. The problem is one of the closing factories was responsible for manufacturing the Wii U Embedded DRAM. Nintendo was responsible for more than half of the load of the factory at peak times, but due to slow sales of the console the company made the plant run at a loss. There’s a possibility that this will have a large impact on Wii U production in the years to come.
Update: Nintendo previously announced that they’ll use TSMC to produce the eDram parts from now on.
