Abstract
A non-volatile memory includes memory cells arranged in rows and columns. Each memory cell includes a program/read portion and an erase portion that share an electrically floating layer of conductive material defining a first capacitive coupling with the program/read portion and a second capacitive coupling with the erase portion. The first capacitive coupling defines a first capacitance greater than a second capacitance defined by the second capacitive coupling. The erase portion is configured so that an electric current extracts charge carriers from the electrically floating layer to store a first logic value in the memory cell. The program/read portion is further configured so that an electric current injects charge carriers in the electrically floating layer to store a second logic value in the memory cell.
