The invention relates to a method for operating a circuit arrangement containing a microcontroller (10) and an EEPROM (11). A first memory area (39) having at least one data set memory (DA1, DA2, DA3) and at least one second memory area (30) also having at least one data set memory (DB1, DB2, DB3) are provided in the EEPROM (11). A pointer (P1, P2, P3) located in a third memory area (31) refers to the respectively valid memory area (29, 30). In one step (53), the microcontroller (10) stores a data set in the invalid memory area (29, 30) and, in a subsequent step (54), changes the pointer (P1, P2, P3) so that the invalid memory area (29, 30) becomes the valid memory area (30, 29). Both steps (53, 54) are cyclically repeated. In the event of a fault during a storage process, a correct data set is available at all times in the memory area (29, 30) indicated as being valid. |
