Abstract:
A magnetic memory includes magnetoresistance effect elements, each of which includes a first ferromagnetic metal layer in which a magnetization direction is fixed, a second ferromagnetic metal layer for a magnetization direction to be changed, and a nonmagnetic layer provided between the first ferromagnetic metal layer and the second ferromagnetic metal layer, a first wiring connected to the first ferromagnetic metal layer of at least one magnetoresistance effect element, spin-orbit torque wirings, each of which is connected to each of the second ferromagnetic metal layers of the magnetoresistance effect elements and extend in a direction intersecting a lamination direction of the magnetoresistance effect element, one first control element connected to the first wiring, one second control element connected to each of first connection points of the spin-orbit torque wirings, and first cell selection elements, each of which is connected to each of second connection points of the spin-orbit torque wirings.
