Memory hub with integrated non-volatile memory

A method of initializing a memory sub-system, comprising:

• accessing a non-volatile memory that contains configuration information specific to the memory sub-system on which the non-volatile memory is located, the configuration information being stored in the non-volatile memory before initialization, the non-volatile memory accessed through a first configuration path from a memory controller of the memory sub-system to the non-volatile memory;
• loading a configuration register of a memory controller with the configuration information from the non-volatile memory through a first configuration path;
• receiving memory access requests from a host system;
• and
• providing the host system access to the non-volatile memory through a second configuration path.

A method of initializing a memory sub-system, comprising:

• loading at least one configuration register of the memory controller with at least a portion of the configuration information through the first configuration path;
• providing a host system access to the non-volatile memory through a second configuration path;
• receiving, by the memory controller, at least one memory access request from the host system;
• and
• accessing, by the memory controller in response to the at least one memory access request and in accordance with the at least a portion of the configuration information, at least a portion of memory of the memory sub-system.
