Abstract:
An apparatus is provided that includes a non-volatile (device storage) memory configured to store data in a plurality of locations. The apparatus also includes a device interface coupled to the non-volatile memory and including a volatile (device storage) shadow memory configured to store an image of the plurality of locations of the non-volatile memory in a corresponding plurality of locations of the volatile shadow memory. The device interface is configured to receive a command across a network bus from a bus controller, and in response thereto, the device interface is configured to write data from the network bus to a location in the non-volatile memory. This write includes the device interface being configured to write the data to the corresponding location in the volatile shadow memory, and thereafter write the data from the corresponding location in the volatile shadow memory to the location in the non-volatile memory.
