Abstract
The floating gate MOS memory cell comprises a substrate of first conductivity type and an electrically isolated biasing electrode of opposite conductivity type on the substrate. An isolated floating gate conductor lies over this electrode in capacitive connection with it. A programming electrode lies adjacent to the floating electrode to introduce electrons into it. An erasing and memorising electrode is provided next to the floating gate to raise electrons to the gate when an electric field is established between the gate and this electrode. The erasing and memorising electrode overlies the bias electrode and is in capacitive connection with it. The biasing electrode may be electrically isolated and a predetermined voltage applied to it. The voltage on the floating gate is detected.
