Abstract
According to one embodiment, a magnetic memory includes a first magnetic unit, a first magnetic layer, a first recording/reproducing element, a first electrode, and a second electrode. The first magnetic unit extends in a first direction. The first magnetic unit includes a plurality of magnetic domains arranged in the first direction. The first magnetic unit has a columnar configuration having a hollow portion. The first magnetic layer is connected to a first end portion of the first magnetic unit, the first magnetic layer extends in a direction intersecting the first direction. The first recording/reproducing element is provided in contact with the first magnetic layer. The first electrode is electrically connected to the first magnetic layer. The second electrode is connected to a second end portion of the first magnetic unit on a side opposite to the first end portion.
