Abstract: Extended commands are transmitted from computer system via a standard interface to a memory system. The computer system accesses logical memory addresses via an application interface using standard read/write commands which are processed by a memory controller in the memory system. A sequence of read commands for at least two logical memory addresses with address values that differ in at least one bit are output by the computer system. The memory controller compares the sequence of different bits with a predefined bit sequence, the magical address sequence. In the event of a match, a subsequent write command for one of the logical memory addresses is used to open a management connection between the computer system and the memory controller, and the useful data contained in the write command are evaluated by the memory controller and are not written to the addressed memory address.
