Abstract: Provided is a single input level shifter. The single input level shifter includes: an input unit applying a power voltage to a first node in response to an input signal and applying the input signal to a second node in response to a reference signal; a bootstrapping unit applying the power voltage to the second node according to a voltage level of the first node; and an output unit applying the input signal to an output terminal in response to the reference signal and applying the power voltage to the output terminal according to the voltage level of the first node, wherein the bootstrapping unit includes a capacitor between the first and second nodes, and when the input signal is shifted from a first voltage level to a second voltage level, the bootstrapping unit raises the voltage level of the first node to a level higher than the power voltage.
