Abstract
A memory device includes a transistor, a capacitor, a plate line, and a bit line. The transistor includes an oxide semiconductor and includes a first end, a second end, and a gate. The capacitor includes a third end and a fourth end. The fourth end is coupled to the second end. The plate line is coupled to the third end. The bit line is coupled to the first end. A second voltage lower than a first voltage is applied to the plate line during a first period over which the first voltage is applied to the gate. A fourth voltage higher than the second voltage is applied to the plate line during at least a part of a second period over which a third voltage lower than the first voltage is applied to the gate.
