A data holding device includes a loop structure portion for holding data by using a plurality of logic gates connected like a loop, and a nonvolatile storage portion for storing data held in the loop structure portion, in a nonvolatile manner by using a hysteresis characteristic of a ferroelectric element. The loop structure portion and the nonvolatile storage portion are driven by being respectively supplied with power supply voltages that are different from each other. |
