Abstract:
1. A signal processing circuit comprising: a circuit; and a nonvolatile storage circuit comprising a first transistor and a node, wherein the circuit is configured to output a first signal to a first terminal of the first transistor when a first power supply potential is supplied to the circuit, wherein the nonvolatile storage circuit is configured to store data corresponding to the first signal in the node electrically connected to a second terminal of the first transistor when a second signal is supplied to a gate of the first transistor, wherein the nonvolatile storage circuit is configured to hold the data while a third signal is supplied to the gate of the first transistor and the first power supply potential is not supplied to the circuit, wherein a potential of the first signal is a first potential and equal to the first power supply potential, wherein a potential of the second signal is a second potential, wherein a potential of the third signal is a ground potential, wherein a potential of the data is the first potential, and wherein the second potential is higher than the first potential.
