Abstract
A resistance variable element of the present invention and a resistance variable memory apparatus using the resistance variable element are a resistance variable element () including a first electrode, a second electrode, and a resistance variable layer () provided between the first electrode () and the second electrode () to be electrically connected to the first electrode () and the second electrode (), wherein the resistance variable layer () contains a material having a spinel structure represented by a chemical formula of (ZnFe)FeO, and the resistance variable element () has a feature that an electrical resistance between the first electrode () and the second electrode () increases by applying a first voltage pulse to between the first electrode () and the second electrode (), and the electrical resistance between the first electrode () and the second electrode () decreases by applying a second voltage pulse whose polarity is the same as the first voltage pulse to between the first electrode () and the second electrode (), and a resistance variable memory apparatus using the resistance variable element ().
