Abstract:
According to one embodiment, a magnetic random access memory includes a plurality of magnetoresistance elements. The plurality of magnetoresistance elements each include a recording layer having magnetic anisotropy perpendicular to a film surface, and a variable magnetization direction, a reference layer having magnetic anisotropy perpendicular to a film surface, and an invariable magnetization direction, and a first nonmagnetic layer formed between the recording layer and the reference layer. The recording layer is physically separated for each of the plurality of magnetoresistance elements. The reference layer and the first nonmagnetic layer continuously extend over the plurality of magnetoresistance elements.
