1. A method of processing and forwarding memory responses in a memory system including a plurality of memory modules, each memory module including a memory hub coupled to memory devices, and the method comprising:

  • storing local memory responses having data retrieved from the memory devices, the local memory responses made in response to associated memory requests requesting the retrieved data from the memory devices;

    storing downstream memory responses having data retrieved from downstream memory modules, the downstream memory responses made in response to associated memory requests requesting data from the downstream memory modules;

    applying in each hub an independent arbitration algorithm to determine an order in which the stored local and downstream memory responses are forwarded to an upstream memory module; and

    forwarding the local and downstream memory responses upstream according to the determined order.
