    • A system and method for calibration of serial links using serial-to-parallel loopback. Embodiments of the present invention are operable for calibrating serial links using parallel links thereby reducing the number of links that need calibration. The method includes sending serialized data over a serial interface and receiving parallel data via a parallel interface. The serialized data is looped back via the parallel interface. The method further includes comparing the parallel data and the serialized data for a match thereof and calibrating the serial interface by adjusting the sending of the serialized data until the comparing detects the match. The adjusting of the sending is operable to calibrate the sending of the serialized data over the serial interface.
    • 一种使用串行到并行环回校准串行链路的系统和方法。 本发明的实施例可用于使用并行链路校准串行链路,从而减少需要校准的链路的数量。 该方法包括通过串行接口发送串行数据,并通过并行接口接收并行数据。 序列化数据通过并行接口环回。 该方法还包括比较并行数据和串行数据以进行匹配,并通过调整串行化数据的发送来校准串行接口,直到比较检测到匹配为止。 发送的调整可以通过串行接口校准串行化数据的发送。

    • A system that calibrates timing relationships between signals involved in performing write operations is described. This system includes a memory controller which is coupled to a set of memory chips, wherein each memory chip includes a phase detector configured to calibrate a phase relationship between a data-strobe signal and a clock signal received at the memory chip from the memory controller during a write operation. Furthermore, the memory controller is configured to perform one or more write-read-validate operations to calibrate a clock-cycle relationship between the data-strobe signal and the clock signal, wherein the write-read-validate operations involve varying a delay on the data-strobe signal relative to the clock signal by a multiple of a clock period. In a variation of this system, the phase detector on the memory chip is configured to receive signals including a clock signal, a marking signal and a data-strobe signal from the memory controller, wherein the marking signal includes a pulse which marks a specific clock cycle in the clock signal. In this variation, the phase detector is configured to use the marking signal to window the specific clock cycle in the clock signal, and to use the data-strobe signal to capture the windowed clock signal, thereby creating a feedback signal which is returned to the memory controller to facilitate calibration of the timing relationship.
