A method, apparatus and/or system of a level shifter circuit having a structure to reduce fall and rise path delay is disclosed. In one embodiment, a level shifter circuit comprise a first set of sequentially coupled pull-up and pull-down sub-circuits cross coupled to a second set of sequentially pull-up and pull-down sub-circuits to generate a positive feedback loop; an output node coupled to a shared node between the first pull-up and pull-down sub-circuits through an output inverter; a pull-up NMOS transistor with a gate contact coupled to the input of the second set, a source contact coupled to an input of the output inverter and a drain contact coupled to the output voltage of the level shifter circuit; and a pull-down NMOS transistor with a gate contact coupled to the input of the second set, a drain contact coupled to an output of the output inverter and a source contact coupled to a ground.
