Abstract:
A communication system includes a storage device having a storage area accessed in one of a page unit and a sector unit; a control device operable to request access to data in a file unit; and a predetermined transmission line for transmitting data between the storage device and the control device. The control device transmits to the storage device via the transmission line a request for access to one of each page and each sector forming a file for which access has been requested, and the storage device sequentially accesses one of a requested page and a requested sector, whereby a request for access to the entire file is realized in the storage area.
