Abstract

Une opération d'écriture d'au moins une donnée dans au moins une cellule-mémoire du type mémoire morte électriquement programmable et effaçable, comprend au moins une étape d'effacement ou de programmation de ladite cellule par une impulsion correspondante d'effacement ou de programmation. On contrôle le bon ou le mauvais déroulement de l'opération d'écriture par une analyse de la forme de ladite impulsion d'effacement ou de programmation (IMPB) au cours de l'étape correspondante d'effacement ou de programmation, le résultat de cette analyse étant représentatif d'un déroulement correct ou non de l'opération d'écriture.
