Abstract: A memory controller receives data and phase-providing signals from a memory device. The phase-providing signal is not a clock signal, but is used by the memory controller to phase align a local data-sampling signal with the incoming data. The memory controller samples the data signal with the data-sampling signal. The memory controller can perform maintenance operations to update the phase relationship between the phase-providing and data-sampling signals.

Abstract: A memory controller having a data receiver to sample data at a sample timing using a strobe signal, wherein the data and the strobe signal are sent by a memory device in connection with a read operation initiated by the memory controller, and a strobe receiver to receive the strobe signal, wherein a phase of the strobe signal has a drift relative to a reference by an amount. The memory controller further having a monitoring circuit to monitor the strobe signal and determine the amount of the drift, and an adjustment circuit to update the sample timing of the data receiver based on the amount of drift determined by the monitoring signal.

Abstract: A communication channel includes a first component having a transmitter coupled to a normal signal source, and a second component having a receiver coupled to a normal signal destination. A communication link couples the first and second components. Calibration logic provides for setting an operation value for a parameter of the communication channel, such as by executing an exhaustive calibration sequence at initialization of the link. A tracking circuit, including a monitoring function, tracks drift in the parameter by monitoring a feedback signal that has a characteristic that correlates with drift in the communication channel, and updates, or indicates the need for updating of, the operation value of the parameter in response to the monitoring function.
