ABSTRACT:
A serial ATA control circuit is provided. The control circuit includes a plurality of serial ATA controllers, a plurality of port controlling circuits, a plurality of switch devices, and a switch controller. Each of the serial ATA controllers has a memory accessing controller and two transceivers. The serial ATA control circuit is connected to at least one serial ATA device through the port controlling circuits. The a plurality of port controlling circuits are connected to corresponding serial ATA controllers through the plurality of switch devices controlled by the switch controller. The connection path between each port controlling circuit and corresponding serial ATA controller is selected by the switch controller to achieve optimal data transfer rate.
