Korea Times writes Apple will dump Samsung and use TSMC's 20nm process to manufacture its A7 mobile processor:
Samsung, which sees Apple’s decision as a negative, plans to maintain growth momentum by expanding its business with NVIDIA through increasing contractual chip orders.
''Apple is sharing confidential data for its next A7 system-on-chip (SoC) with the Taiwan Semiconductor Manufacturing Company (TSMC). TSMC has begun ordering its contractors to supply equipment to produce Apple’s next processors using a finer 20-nanometer level processing technology,’’ said an executive at one of Samsung’s local partners in Korea by telephone, Wednesday.
Unlike conventional memory chips, which are only used to write and store data, application processors are used to power computing devices, and are more profitable and less volatile price-wise.
