Abstract:
A semiconductor device includes a first input circuit to which a first supply voltage is supplied, a second input circuit to which a second supply voltage that is lower than the first supply voltage is supplied, and a control circuit which activates the first input circuit in a first mode and activates the second input circuit in a second mode. The control circuit controls the first input circuit and the second input circuit such that the first input circuit and the second input circuit are activated during a certain time period when switching between the first mode and the second mode.
