Abstract: A power supply voltage control circuit device includes a power supply control circuit, a memory, and an arithmetic processing circuit. The power supply control circuit is configured to control a power supply voltage to be applied to a target circuit, and the memory is configured to store a first processing result when the target circuit is operated by setting the power supply voltage to a first voltage and a second processing result when the target circuit is operated by setting the power supply voltage to a second voltage different from the first voltage. The arithmetic processing circuit is configured to perform verify by reading the first processing result and the second processing result from the memory and output a result of the verify to the power supply control circuit, and wherein the power supply control circuit controls the power supply voltage based on the result of the verify.
