Abstract:
1. A spin transfer type magnetic random access memory comprising: a magnetoresistive effect element including a fixed layer, a recording layer, and a nonmagnetic layer sandwiched between the fixed layer and the recording layer, magnetizations in the fixed layer and the recording layer being perpendicular to a film surface; a source line connected to one terminal of the magnetoresistive effect element; a transistor having a current path whose one end is connected to the other terminal of the magnetoresistive effect element; a bit line connected to the other end of the current path of the transistor, and running parallel to the source line; and a source/sinker which supplies a write current between the source line and the bit line via the magnetoresistive effect element and the transistor, a direction in which a magnetic field generated by the write current having passed through the bit line is applied to the magnetoresistive effect element being opposite to a direction of the write current passing through the magnetoresistive effect element.
