The present invention, in one embodiment, is method for operating an electronic electric meter (100) having current (104) and voltage (106) sensors configured to generate measurements of current and voltage, respectively; a microcomputer (114) coupled to the current and voltage sensors and configured to control operation of said meter (100); a flash memory (118) coupled to said microcomputer (114) and configured to store configuration and metering data. The method includes steps of: mapping requests for data to a physical location of the flash memory (118); organizing the flash memory into logical blocks treated as atomic data units (ADU); and separately managing the ADUs.

L'invention porte dans l'une de ses exécutions sur un procédé de gestion d'un compteur (100) électrique électronique comportant: des détecteurs d'intensité (104) et de tension (106); un micro-ordinateur (114) relié auxdits détecteurs et en assurant la gestion; et une mémoire (118) flash reliée au micro-ordinateur et stockant les données de configuration et de mesure. Ledit procédé consiste: à faire correspondre les demandes de données à des emplacements physiques de la mémoire flash; à organiser la mémoire (118) flash en blocs logiques traités en unités atomiques de données (ADU); et à gérer séparément les ADUs.
