Abstract
A switching resistor comprises a dielectric layer disposed between a first electrode layer and a second electrode layer, the switching resistor having a high resistance state and a low resistance state. The switching resistor is responsive to a voltage bias, applied between the first electrode layer and the second electrode layer, wherein the voltage bias exceeds a threshold to switch from the high resistance state to the low resistance state. The switching resistor is sensitive to photo-illumination to reduce said threshold.
