Abstract
A magnetic memory device includes a conductive member, a stacked body, and a controller. The stacked body includes a first magnetic layer, a second magnetic layer provided between the conductive member and the first magnetic layer, and a third magnetic layer stacked with the first magnetic layer and the second magnetic layer. The controller causes a current to flow in the conductive member. The controller causes a current to flow between the conductive member and the stacked body. The controller is able to identify three or more levels of an electrical resistance value of the stacked body.
