Claim Text:
1. A method of transmitting extended commands to a memory system connected to a computer system via a standard interface, wherein the computer system accesses logical memory addresses via an application interface using standardized write and read commands that are processed by a memory controller in the memory system, the method comprising the following steps: outputting from the computer system via the application interface, a sequence of read commands for at least two logical memory addresses having respective address values that differ in at least one of their bits; comparing with the memory controller the sequence of mutually different bits with a predefined bit sequence to determine whether or not a match exists; in the event of a match, using a subsequent write command for one of the logical memory addresses to open a management connection between the computer system and the memory controller; and evaluating the data contained in the write command by the memory controller and not writing the data to the addressed memory address.
