A magnetic random access memory includes a magnetoresistive effect element having a fixed layer in which a magnetization direction is fixed, a recording layer in which a magnetization direction is reversible, and a nonmagnetic layer formed between the fixed layer and the recording layer, a hollow portion being formed in a center of the recording layer, and the magnetization directions in the fixed layer and the recording layer taking one of a parallel state and an antiparallel state in accordance with a direction of an electric current supplied between the fixed layer and the recording layer, an insulating layer formed in the hollow portion, a wiring connected to one terminal of the magnetoresistive effect element, and a transistor connected to the other terminal of the magnetoresistive effect element.
