Renesas plans to start shipping MRAM samples in 2009. These products will be based on 90nm tech. Last month they said they will ship products in 2010. So samples in 2009, products in 2010. Renesas will also manufacture microcontrollers with embedded MRAM, also to be sold in 2010.
Renesas already has made 130nm MRAM, but they want to make it cheaper and with better power consumption, and this is why they're going to make then at 90nm.
