Abstract:
A magnetic storage device includes a plurality of first wires extending along a first direction and a plurality of second wires extending along a second direction different from the first direction. The plurality of second wires form a grid with the plurality of first wires. The magnetic storage device further includes a plurality of spin orbit torque magnetic random access memory (SOT-MRAM) devices. Each of the plurality of SOT-MRAM devices is disposed at a respective position on the grid. The magnetic storage device further includes write circuitry, including a transistor coupled to each respective first wire of the plurality of first wires, to apply a first write current along the respective first wire in the first direction, and readout circuitry to read a data value stored by a respective SOT-MRAM device.
