Classification: CPC G | IPC G

Claim 9:
10. A data transmission method for providing communication between a host device and a memory card, comprising:
generating, using a data transmission apparatus, a first control signal, thereby connecting said host device to said data transmission apparatus;
generating, using said data transmission apparatus, a second control signal, thereby connecting said data transmission apparatus to said memory card;
in response to said memory card satisfying a first condition, controlling said data transmission apparatus to work in a first transmission mode, 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
in response to said memory card satisfying a second condition, controlling said data transmission apparatus to work in a second transmission mode, 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.
