Patent ID: 7194593

Claim:
A memory hub for a hub-based memory sub-system, comprising: a link interface for receiving memory access requests; an electrically programmable non-volatile memory having memory module configuration information stored therein; a first configuration path coupled to the link interface and the electrically programmable non-volatile memory, the first configuration path configured to provide the link interface access to the electrically programmable non-volatile memory; a second configuration path coupled to the electrically programmable non-volatile memory and configured to provide access to the electrically programmable non-volatile memory; a local serial bus coupled to the electrically programmable non-volatile memory and configured to provide a host system access to the electrically programmable non-volatile memory; and a memory controller coupled to the link interface and further coupled to the electrically programmable non-volatile memory through the second configuration path, the memory controller having registers into which the memory configuration information is loaded, the memory controller operable to access the electrically programmable non-volatile memory through the second configuration path and further operable to output memory requests in response to receiving memory access requests from the link interface and in accordance with the memory configuration information loaded in the registers.
