Abstract
The present invention relates to a single poly EPROM device. The single poly EPROM comprises a floating gate (10), a control gate (12), a source (16) and a drain (18). The control gate (12) is positioned laterally of a channel between the source (16) and the drain (18). The floating gate (10) is positioned above the channel and above the control gate (12). The single poly EPROM device further comprises an additional gate (40) above the floating gate (10) and a control. The control is connected to the additional gate (40) for controlling a voltage at the floating gate (10) in order to prevent the floating gate (10) from being unintentionally charged or discharged.
