A method manufactures non-volatile memory devices integrated on a semiconductor substrate and including a matrix of non-volatile memory cells and associated circuitry. The manufacturing method includes: forming a plurality of electrodes of the matrix memory cells, each electrode including a first dielectric layer, a first conductive layer, a second dielectric layer and a second conductive layer; and forming a plurality of electrodes of transistors of the circuitry each including a first dielectric layer and a first conductive layer. The method also includes forming first coating spacers on the side walls of the gate electrodes of the memory cell and second coating spacers on the side walls of the gate electrodes of the circuitry, the second spacers being wider than the first spacers.
