Abstract: front page image
(EN)In a semiconductor memory device using a nonvolatile memory, such as EEPROM, even in an event that data stored in the nonvolatile memory cannot be correctly read due to a power supply interruption or the like, a recovery program is activated to quickly recover the function as of a memory device. For this purpose, after the activation of the recovery program stored in a ROM, a program (FW2) stored in the EEPROM is transferred to a RAM, and thereafter, a CPU performs a processing based on the program (FW2) transferred to the RAM.
(FR)Dans un dispositif à mémoire à semi-conducteur utilisant une mémoire rémanente, telle qu'une EEPROM, même dans le cas où des données stockées dans la mémoire rémanente ne peuvent être lues correctement du fait d'une interruption d'alimentation en courant ou analogue, un programme de récupération est activé afin de récupérer rapidement la fonction en tant que dispositif à mémoire. Pour ce faire, après l'activation du programme de récupération stocké dans une ROM, un programme (FW2) stocké dans l'EEPROM est transféré à une RAM, et ensuite, une UC exécute un traitement sur la base du programme (FW2) transféré dans la RAM.
