Abstract
A method and apparatus for monitoring an electronic control system, where code of a memory is, in a context of ongoing instruction accesses, transferable via a word line out of the memory to a control unit having a specific word width encompassing code of a plurality of memory cells of the memory and where an additional datum is created in each case for the code of a word width and is storable in the memory, may include an arrangement that, outside the ongoing instruction accesses, checks an entire code of the memory by selecting for each word width a single memory cell to thereby activate a complete word line, that creates a check datum from code of the complete word line, and that compares the check datum with the stored additional datum.
