摘要： Method and device for transmitting outgoing useful signals and an outgoing clock signal. Useful signals and a clock signal are transmitted from a transmitter via a first line pair and a second line pair to a receiver. A first useful signal is transmitted in the form of a modulated difference between the electrical potentials of the first line pair. A second useful signal is transmitted in the form of a modulated difference between the electrical potentials of the second line pair. The clock signal is transmitted in the form of a modulated difference between the average value of the potentials of the first line pair and the average value of the potentials of the second line pair.

A control loop includes at least one phase detector configured to detect a phase shift of a feedback signal relative to a reference clock signal and output a correction signal on the basis of the phase shift detected. At least one control loop filter is configured to output, on the basis of the correction signal, a first control signal and a second control signal, the first control signal being substantially the same as the second control signal except that oscillations are suppressed in the second control signal. At least one first phase generator is configured to output a first clock signal on the basis of the first control signal and the first phase reference signal, wherein the first clock signal is transmitted at least partially as feedback signal to the phase detector.

摘要： A memory system and method is discussed. The memory system includes a memory controller and at least one memory module on which a certain number of semiconductor memory chips and connecting lines are arranged in a respectively specified topology.
