1. A magnetic memory comprising:
an electrode extending along a plane including a first direction and a second direction intersecting with the first direction;
a first wiring extending in the first direction;
a plurality of second wirings between the electrode and the first wiring, the plurality of second wirings extending in the second direction and arranged in the first direction;
plurality of first magnetic members provided corresponding to the first wiring, each of the first magnetic members including a first part electrically connected to the first wiring and a second part electrically connected to the electrode, extending from the first part toward the second part in a third direction intersecting with the first direction and the second direction, and being positioned between neighboring two of the plurality of second wirings when seen from the third direction; and
a control circuit electrically connected to the electrode, the first wiring, and the plurality of second wirings,
wherein, when writing first information to one first magnetic member of the plurality of first magnetic members, the control circuit supplies first current to each of at least two wirings of the plurality of second wirings positioned on one side of the one first magnetic member in the first direction.
