A system includes a memory controller and a plurality of memory devices that are connected in-series to the memory controller. The system operation is synchronous with clock that is provided in a fashion of source synchronous clock structure. The source synchronous clock structure includes a PLL (Phase-Locked Loop) that reshapes an incoming clock and a reshaped clock is provided. The PLL provides a shifted clock in phase of 90 DEG . The phase-shifted clock and data are transmitted from the first device to the second device. Clock phase shift provides a center-edge clock with data to be transmitted. The devices are assigned with unique IDs. The least significant bit of the ID number of the last device is used for determination of clock alignment: edge- or center-aligned clock with data produced by the memory controller.
