    Abstract: A first circuit outputs first information indicating presence/absence of a magnetic wall between two adjacent portions among portions of a magnetic body, and second information based on the combination of magnetization states of the two portions. A first storage circuit stores first bits corresponding to the portions. A most significant bit of the first bits has a value independent of a magnetization state of a corresponding one of the portions, and the first bits have a value based on the first information. A second storage circuit stores the second information. The second circuit causes the first storage circuit to output the first bits when a value of a least significant bit of the first bits matches a value of the second information, and otherwise third bits having inverse values of the first bits.

    Abstract: A magnetic memory of the present embodiment includes an electrode extending along a plane including a first direction and a second direction, a first wiring extending in the first direction, second wirings between the electrode and the first wiring, extending in the second direction and arranged in the first direction, first magnetic members each including a first part electrically connected to the first wiring and a second part electrically connected to the electrode, extending in a third direction, and being positioned between neighboring two of the second wirings when seen from the third direction, and a control circuit. When writing first information to one first magnetic member, the control circuit supplies first current to at least two second wirings positioned on one side of the one first magnetic member in the first direction.

    Abstract: A magnetic memory includes first magnetic members extending along a first direction. First and second wirings are spaced apart from the first magnetic members on a second end side of the first magnetic members. At least one of the first magnetic members is between the first and second wirings in a plan view from the first direction. A second magnetic member has a first portion facing the first wiring and electrically connected to a first magnetic member on one side and a second portion facing the first wiring on an opposite side. The second portion is electrically connected to another first magnetic member. A control circuit causes a current to flow through one of the first wiring or the second wiring when data is written into the first magnetic member that is between the first wiring and the second wiring.
