A data-processing system with an enhanced system controller supporting memory-remapping function. The system controller has an access control circuit, a page/remapping management circuit and an open/remapped address table. The open/remapped address table is used to store mapping tables for indicating the mapping relation of memory segments and addresses dedicated to peripheral devices. The page/remapping management circuit should maintain and use the mapping tables in various operating mode. In addition, the page/remapping management circuit can redirect access requests to proper memory segments according to the mapping table corresponding to the current operating mode. Therefore, peripheral devices can effectively access and process the data stored in various memory segments by the change of the operating modes, not by physical data transfer.
