| 1. A semiconductor memory device comprising:
at least one electrically erasable and programmable non-volatile memory cell including
a layer of gate material,
a floating-gate transistor including a floating gate defined in the layer of gate material, and further including source,
drain and channel regions defining a control gate,
a first active zone, and
a second active zone incorporating the control gate and electrically isolated from the first active zone,
a dielectric zone between a first part of the layer of gate material and the first active zone;
the dielectric zone defining a transfer zone for transferring, during erasure of the memory cell, charges stored in the floating
gate to the first active zone.
