Patent ID: 8315087

Claim:
A magnetic random access memory comprising: a magnetoresistance element; and a current supply section configured to supply a current to said magnetoresistance element, wherein said magnetoresistance element comprises: a first magnetic layer including a first region whose magnetization direction is reversible; a second magnetic layer whose magnetization direction is fixed parallel to a magnetization easy axis direction of said first region; and a non-magnetic layer sandwiched between said first magnetic layer and said second magnetic layer, wherein a domain wall is formed at at least one end of said first region of said first magnetic layer, said second magnetic layer is formed to overlap with at least a part of said first region and at least a part of said one end, and wherein when switching the magnetization direction of said first region, said current supply section applies a write current such that said write current flows between said first magnetic layer and said second magnetic layer through said non-magnetic layer, and wherein a CPP (current perpendicular to a plane) current path is provided such that a CPP write current is supplied to a domain-wall formation position.
