Abstract

L'invention concerne un procédé de commande dynamique de mise hors tension de puce. Le procédé est utilisé dans une application de puce et comprend les étapes suivantes : acquisition d'un premier paramètre de puce de la puce, le premier paramètre de puce indiquant un rapport entre une durée de vie restante de la puce au moment actuel et une durée de vie totale attendue ; détermination dynamique d'un seuil de mise hors tension cible de la puce en fonction du premier paramètre de puce, la valeur du seuil de mise hors tension cible indiquant une limite supérieure du nombre de mises hors tension au sein d'une période cible ; et commande des mises hors tension de la puce en fonction de la valeur de seuil de mise hors tension cible. Après avoir obtenu le premier paramètre de puce, le seuil de mise hors tension cible de la puce est ajusté en fonction du premier paramètre de puce. Par conséquent, la fluctuation de l'amplitude de la charge de puce est réduite, et la fiabilité de la puce est améliorée.
