Title (EN) DISTRIBUTED PROGRAMMED MEMORY CELL OVERWRITE PROTECTION
(FR) PROTECTION CONTRE L'ECRASEMENT DE CELLULES DE MEMOIRE PROGRAMMEES DISTRIBUEES
Abstract: front page image
(EN)A method and circuit for preventing the overprogramming of a memory cell. A fuse circuit is operable to be blown. A combinational logic circuit receives a signal from the fuse circuit, indicating whether or not the fuse has been blown, and controls the programming of the memory cell. The programming of the memory cell is prevented if the fuse circuit has been blown.
(FR)La présente invention concerne un procédé et un circuit pour la prévention de surprogrammation d'une cellule de mémoire. Un circuit à fusible est opérable pour être grillé. Un circuit logique combinatoire reçoit un signal provenant du circuit à fusible, indiquant si le fusible a été grillé ou non, et contrôle la programmation de la cellule de mémoire. La programmation de la cellule de mémoire est interdite si le circuit à fusible a été grillé.
