Abstract

We provide a semiconductor device that can recover degraded data. [Solution] A semiconductor device SDV1 has a circuit ILD, a memory unit MINT, and an arithmetic unit CLP, wherein the circuit has a current source and a first switch, the memory unit has a first transistor and a first capacitor, and the arithmetic unit has a second transistor. The first terminal of the first transistor is electrically connected to the control terminal of the first switch, the first end of the first switch is electrically connected to the output terminal of the current source, and the second terminal of the first switch is electrically connected to the first terminal of the second transistor. When restoring data held in the arithmetic unit, the first transistor is turned ON, and the data held in the memory unit is supplied to the control terminal of the first switch via the first transistor. Depending on the data, the first switch is either ON or OFF, and current is supplied from the current source to the arithmetic unit via the second transistor to replenish the charge in the memory unit's memory unit.
