ABSTRACT:
A method for storing data in memory, in particular adaptation data, includes reading the data out of a first, volatile memory and storing the data in a second, nonvolatile memory. The frequency with which data are stored in the second memory, in particular an EEPROM, is reduced by providing that the data are written in alternation into at least two different memory regions. Moreover, a storage operation of the data occurs only at predetermined time intervals and at a speed of the motor vehicle that is below a predeterminable limit speed. Preferably, a storage operation is performed only when the temperature of the second memory is below a limit temperature.
