A photoelectric conversion apparatus includes a plurality of unit pixels each including a first photoelectric conversion unit, a second photoelectric conversion unit, and a pixel output unit shared by the first photoelectric conversion unit and the second photoelectric conversion unit. The electrodes are spaced from each other by one or more insulating members therebetween, the spacing between the first and third electrodes being greater than that between the first and second electrodes. The conduit adapter includes one or more conduit receiving ports for attachment of electrical conduit. A plurality of word lines are formed over the isolation structures and the charge trapping layer to form the embedded flash ROM structure.
