<p>A semiconductor device is capable of generating an internal voltage having a voltage level that is dependent on an external power supply voltage. The semiconductor device includes an internal voltage generation unit configured to generate a plurality of internal voltages having different voltage levels by using an external power supply voltage, a voltage level detection unit configured to detect a voltage level of the external power supply voltage, and a selection unit configured to selectively output one of the internal voltages in response to a detection result of the voltage level detection unit.</p> |
