Abstract
The present invention discloses a memory card access device, the control method thereof and a memory card access system. Said device comprises: a memory card interface circuit to generate card-read data according to a card-read signal or generate a card-writing signal according to card-writing data; a host interface circuit to generate host-read data according to a host-read signal or generate the host-writing signal according to host-writing data; and a control circuit, coupled to the memory card and host interface circuits respectively, operable to generate the host-writing data by processing the card-read data according to a predetermined cache protocol or generating the card-writing data by processing the host-read data according to the predetermined cache protocol, so as to treat a memory card as a cache device.
