Image Number 4 for United States Patent #7968935.
A reconfigurable semiconductor device is disclosed. The semiconductor device includes a substrate, a first insulating material formed on the substrate, two channels having different polarities, a plurality of terminal electrodes formed on the insulating material and coupled in common with the channels at their opposite ends, a second insulating material formed on the terminal electrodes, and a control gate formed on the second insulating material. The channels have different polarity and a charge storage layer is formed inside the second insulating material. The control gate is applied with a forward bias or a reverse bias and then the bias is cut off. The voltage-current characteristics of the semiconductor device are changed according to an electrical charge created in the charge storage layer.
