ABSTRACT:
A level shifter for use in a semiconductor device, includes: a first transferring unit for transferring an input signal to an inverted output node in response to a negative voltage; a second transferring unit for supplying a power supply voltage to an output node in response to the input signal; and a third transferring unit coupled to the inverted output node and the output node for supplying the negative voltage to the output node in response to an output of the first transferring unit.
