ABSTRACT:
The invention describes a method for adjusting signal propagation times in a memory system in which a controller is connected to at least one memory chip via a plurality of connecting lines for the purpose of transmitting control and data signals and at least one time reference signal. In line with the invention, the propagation time differences between connecting lines are ascertained from the result of echo measurements. To this end a respective transmitted pulse is applied to one end, selected as the transmission end, of the connecting lines in question, while the other end of the connecting lines in question is respectively terminated with a reflective termination. At the transmission end, the echo time which elapses between one edge of the transmitted pulse and the appearance of this edge's echo reflected from the other end is measured. On the basis of the ascertained propagation time differences, regulatable delay devices are set in order to compensate for these propagation time differences. The subject matter of the invention is also circuit arrangements for performing this method.
