Abstract
Methods of electrically programming a diffusion resistor by using trapped charge in a trapped charge region adjacent to the resistor to vary the resistance of the resistor, and the resistor, are disclosed. In one embodiment, a method includes forming a diffusion resistor in a substrate; forming a trapped charge region adjacent to the diffusion resistor; and adjusting a resistance of the diffusion resistor by controlling the trapped charge in the trapped charge region.
