Method and system for terminating write commands in a hub-based memory system

摘要

A memory hub receives downstream memory commands and processes each received downstream memory command to determine whether the memory command includes a write command directed to the memory hub. The memory hub operates in a first mode when the write command is directed to the hub to develop memory access signals adapted to be applied to memory devices. The memory hub operates in a second mode when the write command is not directed to the hub to provide the command's write data on a downstream output port adapted to be coupled to a downstream memory hub.
