Powerchip, Taiwan’s biggest D-Ram company, said on Monday it was exiting the commodity PC D-Ram market in favour of making more specialised chips used in mobile computing devices such as tablets and smartphones.

Frank Huang, chairman, said his company would wind down its business of selling PC D-Ram chips under the Powerchip brand. Instead, Powership would become a contract manufacturer of PC D-Ram chips for long-time partner Elpida of Japan, the world’s third biggest D-Ram company.
