Abstract:
A magnetic memory including a plurality of magnetoresistance effect elements that hold information, each including a first ferromagnetic metal layer with a fixed magnetization direction, a second ferromagnetic metal layer with a varying magnetization direction, and a non-magnetic layer sandwiched between the first and second ferromagnetic metal layers; a plurality of first control elements that control reading of the information, wherein each of the plurality of first ferromagnetic metal layers is connected to a first control element; a plurality of spin-orbit torque wiring lines that extend in a second direction intersecting with a first direction which is a stacking direction of the magnetoresistance effect elements, wherein each of the second ferromagnetic metal layers is joined to one spin-orbit torque wiring line; a plurality of second control elements that control electric current flowing through the spin-orbit torque wiring lines.
