Patent ID: 7504683

Claim:
A non-volatile memory element for the storage of one bit, comprising: a capacitor for recording a value of the bit by breakdown of an insulating layer of said capacitor; a transistor for selecting said element; wherein the transistor and the capacitor are formed within an active region of an integrated electronic circuit substrate, wherein the transistor is of the field-effect MOS type incorporating a source region designed to be connected to a first power supply terminal for the memory element, a gate designed to be connected to a selection terminal for the memory element, and a drain region with electric field drift in a longitudinal direction, wherein the capacitor insulating layer is arranged on top of a surface of the substrate, a first electrode of the capacitor is arranged on the insulating layer and designed to be connected to a second power supply terminal for the memory element, and a second electrode of the capacitor comprises a first portion of the substrate located under the insulating layer and in line with the drain region of the transistor on a side opposite to the gate, wherein the electric field drift drain region comprises a second portion of the substrate within the active region, a doping of said second portion of the substrate being limited to an interval substantially corresponding to a distance between the gate and the first electrode parallel to the longitudinal direction.
