Abstract: A device controller included in a storage device includes a host controller connected to a host memory, a memory controller connected to a plurality of nonvolatile memory devices, a protocol controller configured to control data transfer between the host controller and the plurality of nonvolatile memory devices, and to perform data memory access to a data region of the host memory and non-data memory access to a non-data region of the host memory through the host controller, and a scheduler configured to re-order the data memory access and the non-data memory access such that the non-data memory access to the non-data region is performed after the data memory access to a data chunk has completed, the data chunk being successive data that is allocated within the data region by a physical region page (PRP).
