ABSTRACT:
An array of charge storage devices each including a pair of closely coupled conductor-insulator-semiconductor cells, one a row line connected cell and the other a column line connected cell, is provided on a common semiconductor substrate. Read out of the charges stored in a row of devices is accomplished by obtaining the difference of pairs of signals, one sensed on the row line connecting the selected row of devices and the other of the signals sensed on the row line connecting an adjacent row of devices emptied of stored charge.
