The physics of the memories that store bits in electron spin and atomic polarization rather than trapped charge: how magnetic tunnel junctions, spin-transfer and spin-orbit torque, racetrack domain walls, and ferroelectric switching actually work, what they promise on endurance and latency, the honest 2026 production reality at Everspin and Avalanche, and where storage-class memory really sits in the hierarchy.
