Abstract: The present disclosure provides a method of copying files at a high speed when accesses to both of a local memory physically connected to an access device and a remote memory connected via a wireless network. A file copy controller in the access device generates a FS transfer list in which logical address positions of copy sources and logical address positions of copy destinations are stored, based on file system management information of the local memory and an access list, obtained from another access device, of the remote memory, and inputs the FS transfer list to a non-volatile memory controller connected to the local memory. The non-volatile memory controller copies data between the local memory and the remote memory based on the information stored in the FS transfer list without using a CPU in the access device or an internal bus connected to the CPU.

Abstract: A recording device operates in accordance with an instruction from an access device. The recording device comprising a nonvolatile memory that stores data, a communication unit that receives an instruction issued by the access device, and a memory controller that controls the nonvolatile memory. When a recording instruction for recording data into the nonvolatile memory is received from the access device, the memory controller starts recording of data into the nonvolatile memory. When the memory controller receives from the access device a suspension instruction for suspending the recording of data, the memory controller stores suspension information into the nonvolatile memory, the suspension information indicating a suspended position as a position in a recording area of the nonvolatile memory at which the data is being recorded upon reception of the suspension instruction.

Abstract: A file copy controller in a wireless access device reads file system management information of both of a local memory and a remote memory, generates a FS transfer list in which logical address positions of copy sources and logical address positions of copy destinations are stored, and inputs the FS transfer list to a non-volatile memory controller connected to the local memory. The non-volatile memory controller performs copy operation between the local memory and the remote memory based on the information stored in the FS transfer list without using a CPU in an access device or an internal bus connected to the CPU.
