In one embodiment, a block data transfer interface employing offload data transfer engine in accordance with the present description includes an offload data transfer engine executing a data transfer command set to transfer a block of data in a transfer data path from a source memory to a new region of a destination memory, wherein the transfer data path bypasses a central processing unit to minimize or reduce involvement of the central processing unit in the block transfer. In response to a successful transfer indication, a logical address is re-mapped to a physical address of the new region of the destination memory, instead of a physical address of the original region of the destination memory. In one embodiment, the re-mapping is performed by a central processing unit. In another embodiment, the re-mapping is performed by the offload data transfer engine. Other aspects are described herein.
