Claim 11:
12. A magnetic memory apparatus comprising:
a spin orbit torque (SOT) source extending in a horizontal direction;
a first electrode at one end of the SOT source and a second electrode at another end of the SOT source;
a magnetic fine wire extending on the SOT source in a direction perpendicular to the horizontal direction;
at least one of an insulating layer or a non-magnetic metal layer, the insulating layer or the non-magnetic metal layer on an upper end of the magnetic fine wire;
a fixed layer on the insulating layer or the non-magnetic metal layer;
a third electrode on the fixed layer; and
controller circuitry electrically connected to the first electrode, the second electrode, and the third electrode, wherein
the controller circuitry is configured to move a magnetic domain in the magnetic fine wire upward by flowing a current between the first electrode and the third electrode.
