摘要

P permanent memory cell of the type "merged " (or merged), comprising a floating gate superimposed to the control gate and of the selection. / p & & p & a heterologous modified cell comprises a floating gate 5 superimposed to the control gate and of the selection 9, completed in a single piece. Between the two gates 5, 9 is interposed a dielectric 12 form of silicon oxide, or in a variant, a coupling of the oxide of titanium nitride silicium12 silicium12 and / p
