Abstract
L'invention concerne une mémoire non-volatile effaçable par mots, réalisée suivant la technique à porte flottante. Dans cette mémoire comportant des cellules 1 à au moins un transistor à effet de champ, possédant sur un substrat 2 une porte flottante de mémorisation 13 enserrée par des couches isolantes 10, 17 et une porte de commande 12 isolée, la programmation du transistor à effet de champ, c'est-à-dire la charge de la porte flottante, est réalisée avec le même mécanisme physique que l'effacement ou extinction du transistor à effet de champ, c'est-à-dire la décharge de la porte flottante, à l'aide d'une tension élevée possédant une polarité appropriée et appliquée entre la porte de mémorisation et le substrat. Application notamment aux mémoires de programmes en téléphonie et en télévision.
