    摘要: The present invention refers to a memory system with a controller and a memory device with a communication channel with a data path and a timing path coupling the controller with the memory device. The communication channel has different propagation times for the data path and the timing path exchanging a information signal and a timing signal between the controller and the memory device. The timing signals are used for determining the value of the information signal, and a retiming circuit that is connected with the communication channel compensates, depending on a compensation signal on an input, the delay between the data path and the timing path for exchanging a information signal and a timing signal between the controller and the memory device.
