According to Nikkei, over 20 Japanese and US companies (including TEL, Hitachi, Rensas and Micron) have teamed up to develop MRAM technologies, in particular a new mass production method. They plan to start development in February 2014, and continue to seek more companies from the US and Europe to join. The aim is to complete materials and processes development by 2017 and start mass production by 2018.
This is an exciting development. Hopefully the companies will actually launch this project which could be a breakthrough in MRAM development and commercialization!
