Abstract

A ferroelectric capacitor and another ferroelectric capacitor or dielectric capacitor have one of their electrodes commonly connected to an address selection switching element with its gate connected to a word line and the other of their electrodes connected to first and second plate voltage supply line, respectively. Two operation modes are provided. A first operation mode has a first voltage supplied to a first plate voltage supply line and a second voltage to a second plate voltage supply line. A second operation mode has the second voltage supplied to the first plate voltage supply line and the first voltage to the second plate voltage supply line.
