Assignee: SUZHOU BAYHUB ELECTRONICS TECHNOI
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 0:
1. A data transmission apparatus for providing communication between a memory card and a host device, said data transmission apparatus comprising:
a first port connected to a control module in said data transmission apparatus and controlled by a first control signal;
a second port connected to a card signal selecting module in said data transmission apparatus and controlled by said first control signal;
a first signal path connecting said control module and said card signal selecting module and controlled by a second control signal, wherein said data transmission apparatus implements signal transmission between said control module and said card signal selecting module via said first signal path; and
a second signal path connecting said host device and said card signal selecting module and controlled by said second control signal, wherein said host device transmits signals to said card signal selecting module via said second signal path,
wherein when said memory card satisfies a first condition, said data transmission apparatus works in a first transmission mode,
wherein in said first transmission mode, said first control signal selects said first port to be turned on, said second control signal selects said 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,
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 said second port to be turned on, said second control signal selects said 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.
