    摘要: A method, system, and computer program product are provided for adjusting write timing in a memory device based on a command protocol. For instance, the method can include enabling a write clock data recovery (WCDR) mode of operation. The method can also include transmitting WCDR data from a processing unit to the memory device during the WCDR mode of operation and another mode of operation of the memory device. Based on a phase shift in the WCDR data, a phase difference between a signal on a data bus and a write clock signal can be adjusted. Further, the method can include transmitting the signal on the data bus based on the adjusted phase difference between the signal on the data bus and the write clock signal.

    摘要: A method, system, and computer program product are provided for adjusting write timing in a memory device based on results of an error detection function. For instance, the method can include determining a write timing window between a signal on a data bus and a write clock signal based on the results of the error detection function. The method can also include adjusting a phase difference between the signal on the data bus and the write clock signal based on the write timing window. The memory device can recover data on the data bus based on the adjusted phase difference.

    摘要: Embodiments described herein include a method and system for synchronizing clocks between coupled integrated circuits (ICs) in a computer system. According to an embodiment, a dedicated timing pin is provided on a first IC. The first IC configures a second IC to change a pin assignment, so that the second IC interprets a signal sent on the timing pin by the first IC and received on the reassigned pin as a request to transmit a return signal. The return signal is received on the timing pin. The return signal is used to determine whether timing should be adjusted by the first IC. In an embodiment a clock and data recover (CDR) circuit compares the signal sent to the signal received in order to make the determination. In an embodiment the first IC is a processor-based device, and the second IC is a memory device controlled by the first device.
