    摘要: A method of protecting a microcomputer system against manipulation of data stored in a memory arrangement of the microcomputer system, in particular a control program stored there. Checking mechanisms are executed at preselectable points in times to check for manipulation of the data. To permit effective blocking of manipulated data stored in the memory arrangement, new data is stored at least partially in a volatile memory, in particular in a random access memory, in reprogramming or new programming of the memory arrangement, the checking mechanisms are executed and the portion of the new data stored in the volatile memory is copied to the memory arrangement if no manipulation of the new data has been detected.

    摘要: A control unit for an internal combustion engine including a microcontroller having an integrated memory for receiving memory contents, in which the microcontroller is configured so that, in a first operation, memory areas are definable for providing a final memory protection and/or memory areas are provided with a preliminary memory protection, and, in a second operation, the defined memory areas or the memory areas provided with a preliminary memory protection are providable with a final memory protection.
