ABSTRACT:
A memory element comprises a first electrode, a second electrode, and a resistance variable film2which is disposed between the first and second electrodes to be connected to the first and second electrodes, a resistance value of the resistance variable film2varying based on voltage applied between the first and second electrodes, the resistance variable film2includes a layer2amade of Fe3O4and a layer2bmade of Fe2O3or a spinel structure oxide which is expressed as MFe2O4(M: metal element except for Fe); and the layer2amade of Fe3O4is thicker than the layer2bmade of Fe2O3or the spinel structure oxide.
