Abstract
A race track magnetic memory device includes a magnetic fine wire having a plurality of magnetic domains, a magnetic tunnel junction element comprising a pinned layer and an insulating layer, and a spin-orbit torque (SOT) generator. An easy axis of the magnetic fine wire is substantially perpendicular to a contact surface of the magnetic fine wire and the SOT generator. The magnetic tunnel junction element and the SOT generator are disposed on a magnetic domain write region of the magnetic fine wire. Data is written by generating spin-transfer torque at magnetization of the magnetic domain write region by flowing a first current in the magnetic tunnel junction element and by generating spin-orbit torque at the magnetization of the magnetic domain write region by flowing a second current in the SOT generator.
