1. A magnetic memory, comprising:
a plurality of first magnetic members, each extending along a first direction and having a first end portion and a second end portion;
a first wiring and a second wiring on a second end side of the first magnetic members spaced apart from the first magnetic members, the first and second wirings extending along a second direction intersecting the first direction, and adjacent to each other in a third direction intersecting the first direction and the second direction, with at least one of the first magnetic members being at a position between the first wiring and the second wiring in a plan view from the first direction;
a second magnetic member including a first portion facing a first side surface of the first wiring and a second portion facing a second side surface of the first wiring on a side opposite to the first side surface, the first portion being electrically connected to one of the first magnetic members on a side of the first portion closer to the first side surface, the second portion being electrically connected to another one of the first magnetic members on a side of the second portion closer to the second side surface; and
a control circuit electrically connected to the first wiring and the second wiring, wherein
the control circuit is configured to cause a current to flow through one of the first wiring or the second wiring when data is written into the one of the first magnetic members that is positioned between the first and second wirings in the plan view.
