Claim 0:
1. A magnetic memory device comprising:
a spin orbit torque (SOT) source configured to generate SOT; and
a magnetic fine wire having an end contacting a main surface of the SOT source,
wherein a direction of SOT generated by the SOT source is perpendicular to a direction in which the magnetic fine wire extends,
a plurality of magnetic domains, in the magnetic fine wire, each of the plurality of magnetic domains corresponding to a uniform magnetic direction extending parallel to or antiparallel to the direction in which the magnetic fine wire extends, and
the magnetic fine wire is configured to store a plurality of bits, each of the plurality of bits corresponding to respective ones of the plurality of magnetic domains, and each of the plurality of magnetic domains separated by a magnetic domain wall extending perpendicular to the extension direction of the magnetic fine wire.
