Abstract
Apparatus and method for coupling high voltages for a semiconductor device via high voltage switches are disclosed. A high voltage switch includes a switch and a level shifter. The switch is defined between a voltage source and a voltage output. An enable line is coupled to a first transistor of the switch. The level shifter includes an input and an output. A characterization line is coupled to the input of the level shifter and the output of the level shifter is coupled to a second transistor of the switch. The level shifter further includes a power rail that is coupled to the switch between the first transistor and the second transistor.
