Abstract
A semiconductor device includes a first power supply terminal, a second power supply terminal, a comparison circuit coupled to the first power supply terminal and the second power supply terminal to produce at an output node thereof a signal responsive to a difference between a potential of the first power supply terminal and a potential of the second power supply terminal, and a core circuit coupled to the output node of the comparison circuit to perform a test operation in response to the signal.
