Abstract
A semiconductor device includes a voltage supply circuit including a first pad to which a first source voltage that is generated from an external power source is applied and a second pad to which a second source voltage that is generated from the external power source is applied and configured to generate an internal voltage based on at least one of the first source voltage and the second source voltage and an internal voltage supply circuit configured to generate the internal voltage by supplying less than all of the second source voltage to the first source voltage when a level of the second source voltage is a set voltage level or higher, when generating the internal voltage based on the first source voltage.
