Apparatus and method for improved data restore in a memory system

A process of interacting with a memory module to restore data backed up from volatile memory to nonvolatile memory of the memory module involves a host system configuring the volatile memory of the module to interoperate with a host memory controller via a DIMM memory interface to the module; the host configuring a controller of the module to copy data from the nonvolatile memory to a peripheral I/O bus, the configuration of the controller of the module carried out via the peripheral I/O bus; a host I/O controller receiving the data copied to the peripheral I/O bus and communicating the received data to a host memory controller; and the host memory controller copying the received data to the volatile memory via the DIMM memory interface, thus completing a restore of the data from nonvolatile memory to the volatile memory.
