Abstract
A variety of applications can include a high voltage switch configured to translate supply voltages or other voltages to specific magnitudes in memory devices, with the high voltage switch designed to provide enhanced lifetime of components of the high voltage switch. A high voltage switch can include a high voltage diode coupled to an output node and to a gate of a high voltage transistor coupled to the output node. The high voltage diode can provide feedback of an output voltage to the gate of the high voltage transistor to relieve Fowler-Nordheim stress on the dielectric coupled to the gate in the transistor, where large shifts in threshold voltage of the transistor could otherwise result from the Fowler-Nordheim stress. The high voltage diode can be structured using a high voltage field effect transistor. Additional devices, systems, and methods are discussed.
