Abstract

In a system for the storing of information, having a non-volatile memory comprising a plurality of memory locations, information is stored in each case in succession in two memory locations, an uneven number of which are utilized in cyclic sequence. Upon a reading after reconnection, the information is read out from, in each case, two adjacent memory locations, advancing in each case by one memory location, and tested for agreement. From the sequence of agreements and disagreements, the memory location having the valid information is determined. For the checking of the connection between a processor and the non-volatile memory, the information of at least one additional memory location is read out from time to time and new information is then written into the further memory location, which information is thereafter read. The new information and the previous information are compared with each other. If they agree then there is a disturbance in the connection.
