Abstract: 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.

Abstract: A method for testing an integrated circuit and an integrated circuit. The integrated circuit has an internal testing structure which may be accessed via an internal test access port and a control bus which is conducted to the outside via control ports, it being possible to switch over between a running mode and a test mode so that, in the test mode, the test access port is accessed via the control ports and the control bus, thus testing the integrated circuit.

Abstract: 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.

Abstract: A method for providing dynamic memory management, and a memory device and a system for implementing this method. In addition, a computer program and a computer program product. The memory device includes a first memory block, in which a startup program is stored, and a number of additional memory blocks. The first memory block and the additional memory blocks are connected by a chained list, which is executed at the time of checking of the memory device. The startup program obtains data necessary for a check from the memory blocks themselves.
