Abstract: Synchronization is provided in a memory system. During memory write operations a timing reference signal is transmitted with control signals to a memory device, and a calibration signal is received from the memory device. An internal clock signal is adjusted based on the calibration signal, and a data signal is then transmitted according to the internal clock. In this manner, the data is synchronized such that the data is accurately sampled according to the local clock signal.
