Classification: CPC G | IPC G

Claim 17:
18. A data transmission system including a host device, a data transmission apparatus, and a memory card, and configured to generate a first control signal and a second control signal,
wherein said first control signal is configured to control a signal path between said host device and said data transmission apparatus;
wherein said second control signal is configured to control another signal path between said data transmission apparatus and said memory card;
wherein when said memory card satisfies a first condition, said data transmission apparatus works in a first transmission mode, and wherein in said first transmission mode, said first control signal selects a first port to be turned on, said second control signal selects a first signal path to transmit signals, and said data transmission apparatus connects said host device and said memory card via said first port and said first signal path; and
wherein when said memory card satisfies a second condition, said data transmission apparatus works in a second transmission mode, and wherein in said second transmission mode, said first control signal selects a second port to be turned on said second control signal selects a second signal path to transmit signals, and said data transmission apparatus connects said host device and said memory card via said second port and said second signal path.
