Abstract
A non-volatile memory device includes a network of non-volatile memory cells, each comprising a floating-gate transistor, said network of cells being intended to store data in the form of a set of data words. The device includes a circuit which detects loss of charges stored in the cells and then reprograms the cells for which a loss of charges has been detected so as to restore the level of stored charges.
