Battle lines were drawn across the global D-ram memory chip industry on Thursday as Micron of the US and its Taiwanese partner ruled out joining the Taiwan government's industry restructuring plan, centred around the new established Taiwan Memory Company.

Micron, the world's fourth biggest D-Ram maker, said it had “decided not to participate in TMC as it is currently structured”. At the same time Nanya Technology, its Taiwan partner, asked for “the same support from the [Taiwan] government” that Taiwan Memory will receive.
