Claim:
1. A magnetic memory element, comprising: a first magnetic unit extending in a first direction, having an easy magnetization axis in a direction intersecting the first direction, and being capable of retaining a plurality of magnetic domains in the first direction; a second magnetic unit provided to be separated from the first magnetic unit, the second magnetic unit extending in the first direction, having an easy magnetization axis in a direction intersecting the first direction, and being capable of retaining a plurality of magnetic domains in the first direction; a third magnetic unit connected to one end in the first direction of the first magnetic unit and one end in the first direction of the second magnetic unit, the third magnetic unit having an easy magnetization axis in a second direction intersecting the first direction; a read/write unit including a nonmagnetic layer and a pinned layer, the nonmagnetic layer being connected to the third magnetic unit, the pinned layer being connected to the nonmagnetic layer; a first electrode connected to one other end in the first direction of the first magnetic unit; a second electrode connected to one other end in the first direction of the second magnetic unit; a third electrode connected to the read/write unit; a first current source causing a current to flow between the third electrode and at least one of the first electrode or the second electrode; and a second current source causing a current to flow between the first electrode and the second electrode.
