Abstract

An error detection device for a command decoder is described, the command decoder reading out an associated sequence of control signal words from a command memory based on an input word, wherein the sequence of control signal words has at least one control signal word, having: a controller designed to provide the input word at a first time and the input word at a second time for reading out the command memory, wherein the second time is delayed with respect to the first time, to effect a readout of the sequence of control signal words at a first time and a readout of the sequence of control signal words at a second time; and a comparator designed to receive and compare the associated sequences of control signal words read out at the first and second times, and to output a signal indicating an error if the associated sequences of control signal words read out at the first and second times are different.
