Abstract:
1. A magnetic random access memory comprising: a semiconductor substrate; a transistor having a gate electrode formed above a surface of the substrate, and a first impurity diffusion region and second impurity diffusion region which sandwich a channel region below the gate electrode; a first conductive plug formed on the first impurity diffusion region; a recording element formed on the first plug, including a plurality of stacked layers, and configured to hold information in accordance with an internal magnetization state; a first signal line formed on the recording element; a second conductive plug formed on the second impurity diffusion region; an electrical conductor formed on the second plug and including a plurality of layers identical to the plurality of layers forming the recording element, an area of a shape of the electrical conductor, which is projected onto the surface of the substrate, being larger than that of a shape of the recording element, which is projected onto the surface of the substrate; and a second signal line formed on the electrical conductor.
