Claim 15:
16. A magnetic memory apparatus comprising:
a magnetic memory device including,
a vertical magnetic recording layer in which a length of an extension direction thereof is two times or more a cross-sectional length of the vertical magnetic recording layer in a direction perpendicular to the extension direction,

a non-magnetic layer on an upper surface of the vertical magnetic recording layer in the extension direction,
a fixed layer on the non-magnetic layer in the extension direction,

a spin orbit torque (SOT) generator connected to a lower surface of the vertical magnetic recording layer and configured to generate a SOT,
a first electrode and a second electrode connected to the SOT generator and configured to pass a current through the SOT generator in a direction perpendicular to a direction of the SOT, and
a third electrode connected to the fixed layer and configured to pass a current through the vertical magnetic recording layer; and

a controller, the controller being configured to control a current to flow in a direction corresponding to write information between the first electrode and the second electrode.
