Abstract
A power supply circuit of a semiconductor device includes a voltage generation circuit, first and second terminals, and a switch circuit. The voltage generation circuit is configured to generate an operation voltage of the semiconductor device. The first terminal is configured to be at a reference voltage corresponding to an external power supply voltage that is supplied from an external source external to the semiconductor device. The second terminal is connectable to a measuring device. The switch circuit is configured to cause one of the operation voltage and the reference voltage to be output toward the second terminal and then the other of the operation voltage and the reference voltage to be output toward the second terminal.
