Abstract
Provided is a semiconductor device that may include a switching device having a negative threshold voltage, and a driving unit between a power terminal and a ground terminal and providing a driving voltage for driving the switching device. The switching device may be connected to a virtual ground node having a virtual ground voltage that is greater than a ground voltage supplied from the ground terminal and may be turned on when a difference between the driving voltage and the virtual ground voltage is greater than the negative threshold voltage.
