A nonvolatile memory device having a field effect transistor for storing, which includes source and drain regions in a semiconductor substrate with a channel region interposed between them and a gate electrode above the channel region with a ferroelectric gate film sandwiched between them. Barrier metal is formed in contact with the source region of the field effect transistor for storing to make a Schottky diode in serial connection with the field effect transistor for storing. In reading information, voltage is applied to a serial circuit consisting of the field effect transistor for storing and the Schottky diode to turn the Schottky diode on.
