<p>A semiconductor device is provided to reduce a time to return the voltage of the power line of the internal circuit and suppress the noise of the power supply. A semiconductor device includes a first power line, a second power line, a third power line, a first switch connecting and separating a first power line and third power line, and a second switch connecting or separating the second power line and the third power line. A control circuit controls the first switch to connect the first power line and the third power line, and it controls the second switch to connect the second power line and the third power line.</p> |
