Patent 7746684 was granted and assigned to Industrial Technology Research Institute on June, 2010 by the United States Patent and Trademark Office.
An operating process of an organic device includes performing a programming process and an erasing process. The programming process includes steps of applying a first positive bias from the first electrode to the second electrode on the organic device so that a conductive state of the organic device is switched to be a first turn-on state when the organic device is in a turn-off state and applying a negative bias from the first electrode to the second electrode on the organic device so that the conductive state of the organic device is switched to be a second turn-on state when the organic device is in the first turn-on state. The erasing process includes a step of applying a second positive bias from the first electrode to the second electrode on the organic device so that the conductive state of the organic device is switched to be the turn-off state.
