Current-saving storage concept for electronic modules in a motor vehicle (as amended)

Abstract

A device for storing electronic module data in a motor vehicle in a current-saving manner including: a first volatile memory area, supplied with current only if the electronic module is in normal operation, a second volatile memory area, supplied with current during normal operation and during a quiescent mode. A method for storing data of an electronic module in a motor vehicle in a current-saving manner includes: storing data in the second volatile memory area. The data are updated at least during the quiescent mode. Storing data in the first volatile memory area. The data in the first volatile memory area are not updated during the quiescent mode. Switching off the current supply of the first volatile memory area as soon as the electronic module leaves normal operation. Switching on the current supply of the first volatile memory area as soon as the electronic module is in normal operation.
