A method for an FPGA includes coupling a first electrode of a first resistive element to a first input voltage, coupling a second electrode of a second resistive element to a second input voltage, applying a first programming voltage to a shared node of a second electrode of the first resistive element, a first electrode of the second resistive element, and to a gate of a transistor element, and changing a resistance state of the first resistive element to a low resistance state while maintaining a resistance state of the second resistive element, when a voltage difference between the first programming voltage at the second terminal and the first input voltage at the first terminal exceeds a programming voltage associated with the first resistive element.
