Abstract

La présente invention concerne un procédé embarqué sur dispositif discret ou intégré d'écriture d'un programme incluant code et données dans une mémoire non-volatile, le procédé comprenant des étapes de : • pour une pluralité de zones de la mémoire non-volatile, détermination (102) sans données préalables d'un état d'usure de la zone avant écriture du nouveau programme, • réception et utilisation (106) de données de condition d'accès à une portion du programme depuis la mémoire volatile, la détermination desdites données étant mise en œuvre avant que la portion du programme ne soit écrite dans la mémoire non-volatile , • sélection (110, 116) d'au moins une des zones de la mémoire non-volatile où écrire la portion du programme, en fonction des données et des états d'usure déterminés.
