Intel says it will present a new paper detailing its MRAM research at the International Electron Devices Meeting (IEDM) in early December 2018. This is the first time we hear of any MRAM R&D at Intel which is great news, even if it just a research paper.
Intel has apparently successfully integrated embedded MRAM into the company's 22nm FinFET CMOS technology on full 300mm wafers. The magnetic tunnel junction-based memory cells are built from dual MgO magnetic tunnel junctions (MTJs) separated by a CoFeB-based layer in a 1 transistor-1 resistor (1T-1R) configuration in the interconnect stack. Intel has manufactured a 7.2Mbit array with reported data retention figures in excess of 10 years and write endurance of greater than 10^6 cycles.
