Abstract
The disclosure provides a communication system between dies and a repairing method for lanes between dies. The communication system includes a transmitting device disposed on a first die and a receiving device disposed on a second die. During the transmission process in which the transmitting device transmits a data unit stream to the receiving device through a native lane, after the native lane is determined to be a degraded lane, the transmitting device transmits a synchronization flag to the receiving device through a redundant lane to notify a repair time point. During the uninterrupted transmission process of the data unit stream, the transmitting device uses the redundant lane instead of the degraded lane based on the repair time point, and the receiving device uses the redundant lane instead of the degraded lane based on the repair time point notified by the synchronization flag.
