Abstract
Pulse voltages Vand Vare applied to the first upper gate electrode and the second upper gate electrode, respectively, for a period Twhich is shorter than a period necessary to invert all the polarizations included in the ferroelectric film, while voltages Vs, Vd, and Vare applied to the source electrode, the drain electrode, and the lower gate electrode film, respectively, so as to increase the values of the widths WRHand WRHand so as to decrease the value of the width WRL. The pulse voltages Vand Vhave a smaller voltage than a voltage necessary to invert all the polarizations included in the ferroelectric film. The voltage Vs, the voltage Vd, the voltage V, the pulse voltage V, and the pulse voltage Vsatisfy the following relationship: Vs, Vd, V<V, V
