ABSTRACT:
A magnetic random access memory includes a bit line running in a first direction, a first word line running in a second direction different from the first direction, and a memory element having a magnetoresistive effect element including a fixed layer having a fixed magnetization direction, a recording layer having a reversible magnetization direction, and a nonmagnetic layer formed between the fixed layer and the recording layer, the magnetization directions in the fixed layer and the recording layer being perpendicular to a film surface, and a heater layer in contact with the magnetoresistive effect element, the memory element being connected to the bit line, and formed to oppose a side surface of the first word line such that the memory element is insulated from the first word line.
