Scientific Foundation & Mechanism
Non-volatile memory that stores each bit in the magnetic state of a magnetic tunnel junction, so data persists without power and can be rewritten without an erase step. Freescale began selling the first commercial MRAM chip, a 4 Mbit part, in July 2006; Everspin, spun out of Freescale in 2008, is the leading discrete supplier (FY2024 revenue $50.4 million) and builds STT-MRAM with GLOBALFOUNDRIES, including a 1 Gb DDR4 device and embedded MRAM on GF's 22FDX platform. Spin-orbit-torque MRAM is the next write mechanism and is not yet in volume production.
