Abstract

An array of floating gate semiconductor devices wherein the floating gate member 16 associated with a particular device extends across the drain-channel region junction with a leading edge that terminates over the channel region. The associated control gate 20 extends across the channel region. It is insulated from the floating gate, and has a leading edge that terminates over the drain region and a trailing edge that terminates over the source region. The displacement of the trailing edge of the floating gate from the source region permits the control gate of each device, in a given row, to be connected to a common line 40 and the source and drain regions of a given device to be the same regions as the drain and source regions, respectively, of the next adjacent device on either side in a given row. The common source-drain regions of respective columns are connected in common to form an addressable array. <IMAGE>
