Abstract:
1. A thin film storage device, comprising: a first electrode formed over a surface of a substrate; a variable resistance thin film formed by a material whose resistance changes in accordance with a voltage pulse and having a spinel structure formed over a surface of the first electrode; a second electrode formed over a surface of the variable resistance thin film; and an electric circuit configured to apply a voltage pulse to the first and second electrodes, wherein a resistance in a bulk state of the material which constitutes the variable resistance thin film changes in accordance with a lattice strain generated by a Jahn-Teller effect, a thickness of the variable resistance thin film is equal to or less than 200 nm, and said first electrode directly contacts a first surface of said variable resistance thin film, and said second electrode directly contacts a second surface of said variable resistance thin film.
