Abstract:
A magnetic random access memory includes a memory cell element which includes a first fixed layer, a first recording layer in which a magnetization direction reverses on the basis of a first threshold value, and a first nonmagnetic layer formed between the first fixed layer and the first recording layer, a first interconnection connected to one terminal of the memory cell element, a transistor whose current path has one end connected to the other terminal of the memory cell element, a second interconnection connected to the other end of the current path, and a first resistance change element electrically connected to the memory cell element, and having a resistance value which changes on the basis of a second threshold value.
