Abstract
L'invention concerne un dispositif de traitement de données comportant au moins une unité de traitement (2) de données, et au moins une mémoire non volatile (5) effaçable et reprogrammable électriquement, au moins sous contrôle partiel de l'unité de traitement.
Le dispositif est caractérisé en ce qu'il comporte des moyens de détection (8) d'un signal de demande de réinitialisation des registres du dispositif, commandant des moyens (7) entraînant le blocage de l'application d'au moins un signal (Vpp, WE, EE) nécessaire à la programmation de la mémoire non volatile (5) au moins lorsque ledit signal de demande de réinitialisation (RAZ) des registres du dispositif possède un niveau suffisant (RAZ1) pour activer la réinitialisation.
Une application particulièrement intéressante de ce dispositif concerne les microprocesseurs monolithiques et/ou autoprogrammables.
