Abstract
A level shifter and method of level shifting between an input signal and an output signal which may realize improvement s in operating speed and reductions in power consumption. An example level shifter may include a pull-up signal generation unit outputting a pull-up signal at a voltage level that is a given voltage level higher than a voltage level of an input signal, a pull-up unit pulling-up an output signal in response to the pull-up signal to generate the output signal with a shifted level, and a pull-down unit pulling-down the output signal in response to the input signal.
