Radio access unit and a radio access system

File copy controller of internal radio access device reads the local memory, both remote memory file system management information to generate a copy source, FS transfer list storing logical address position of the copy destination, which is connected to the local memory input to the non-volatile memory controller. Nonvolatile memory controller based on information stored in the FS transfer list, without using the internal bus connected to the access device inside the CPU and CPU, performed local memory, the copy processing between the remote memory.
