Abstract: An embodiment of non-volatile memory device integrated in a chip of semiconductor material is proposed. The memory includes at least one sector of a plurality of memory cells; each sector includes a storage region of a first type of conductivity and a further storage region of a second type of conductivity. Each memory cell includes a first region and a second region of the second type of conductivity, which are formed in the storage region for defining a storage transistor of floating gate MOS type of the first type of conductivity; the memory cell likewise includes a further first region and a further second region of the first type of conductivity, which are formed in the further storage region for defining a further storage transistor of floating gate MOS type of the second type of conductivity. The memory cell also includes a common floating gate of the storage transistor and the further storage transistor.
