A semiconductor memory and a data processing system having hardware for carrying out a method for the improved internal monitoring of addressing circuits in semiconductor memories or in a data processing system, in which logic levels addressing lines are tapped off, the actually selected address or subaddress is represented by additional address bit lines, the actually accessed address/subaddress is recovered using the address bit lines, and the actually selected address/subaddress is compared with the applied address/subaddress, obtained from the additional address bit lines, in order to recognize an error in the addressing circuit.
