Abstract: A memory hub having an integrated non-volatile memory for storing configuration information is provided. The memory hub includes a high-speed interface for receiving memory access requests, a non-volatile memory having memory configuration information stored therein, and a memory controller coupled to the high-speed interface and the non-volatile memory. The memory controller includes registers into which the memory configuration information is loaded and is operable to output memory requests in response to receiving memory access requests from the high-speed interface and in accordance with the memory configuration information loaded in the registers. A method for initializing a memory sub-system is also provided. The method includes loading configuration registers of a plurality of memory hubs with the configuration information provided by a respective one of a plurality of embedded non-volatile memories integrated in the respective memory hub.

Abstract: A method and apparatus for providing a preferred operating voltage to a memory device as specified by a stored configuration parameter. The apparatus includes a nonvolatile memory configured to store a preferred memory device voltage configuration corresponding to a preferred operating voltage of the memory device. The preferred memory device voltage configuration is readable by a host and the circuit is responsive to a command to modify the voltage to the memory device in accordance with the preferred memory device configuration. The voltage to the memory device is modified for improved performance and compatibility of the memory device with a host system.
