Abstract
An integrated memory circuit includes at least one memory cell formed by a single transistor whose gate (GR) has a lower face insulated from a channel region by an insulation layer containing a succession of potential wells, which are substantially arranged at a distance from the gate and from the channel region in a plane substantially parallel to the lower face of the gate. The potential wells are capable of containing an electric charge which is confined in the plane and can be controlled to move in the plane towards a first confinement region next to the source region or towards a second confinement region next to the drain region so as to define two memory states for the cell.
