NEC
The NEC Group focuses on two core areas of business: integrated IT / network solutions and semiconductor.
NEC has been developing MRAM technologies for a long time, collaborating with both TMSC and Toshiba. NEC are also working on perpendicular MRAM. NEC planned to commercialize pMTJ-based MRAM chips by 2010, but that plan did not materialize, and it is not clear if NEC still develops MRAM technologies.
