At a first timing of a read operation, voltages of the first through third wirings are larger than voltages of the fourth and fifth wirings. At a second timing, voltages of the second and third wirings are larger than voltages of the fourth and fifth wirings. At a third timing, voltages of the fourth and fifth wirings are larger than their voltages at the second timing.
