US Patent 10055236 Runtime data storage and/or retrieval

A data storage device includes a memory and a controller. The controller is configured to, in response to a transition from a low power state to an active state, load runtime data to a volatile memory of the controller from a memory of a device coupled to the controller via an interface and, concurrently with loading the runtime data from the memory of the device to the volatile memory of the controller, load other data from the non-volatile memory to the volatile memory of the controller.
