A memory cell includes a ferroelectric capacitor and a transistor connected between one side of the capacitor and a bit line. A drive circuit includes an operational amplifier having an output, an inverting input, and a non-inverting input. A plate line is connected between the other side of the capacitor and the output. The non-inverting input is connected to a data-in line through a first resistor and to the bit line through a second resistor. The inverting input is connected to a constant voltage source through a third resistor, and to the plate line through a fourth resistor. A first buffer amplifier is connected between the bit line and the second resistor, and a second buffer amplifier is connected between the plate line and the fourth resistor. Voltage is connected to the other one of the operational amplifier inputs.
