PROBLEM TO BE SOLVED: To provide a highly reliable semiconductor device, a semiconductor device with a reduced circuit area, a memory element having favorable characteristics, a highly reliable memory element, or a memory element with increased storage capacity per unit volume.SOLUTION: A semiconductor device includes a capacitor and a switching element. The capacitor includes a first electrode, a second electrode, and a dielectric. The dielectric is positioned between the first electrode and the second electrode. The switching element includes a first terminal and a second terminal. The first terminal is electrically connected to the first electrode. The following steps are sequentially performed: a first step of turning on the switching element in a first period, a second step of turning off the switching element in a second period, and a third step of turning on the switching element in a third period after the second step.SELECTED DRAWING: Figure 1 |
