Abstract
A bitcell may include an insulating region, a first doping proximate to the insulating region, and a second doping surrounding the first doping. The second doping can be characterized by a higher gate voltage breakdown than the first doping. Also, the bitcell may include a gate terminal, and the bitcell may be configured for programming by a voltage on the gate terminal that results in a conductive hole selectively burned in the insulating region between the gate terminal and the first doping.
