  • Patent number: 8738827
    Abstract: An interface circuit provides communication between a memory card and a host device. The interface circuit includes first and second sets of pins and a control unit. The control unit enables the first set of pins and disables the second set of pins when transferring a first set of signals in a first mode via the first set of pins, and disables the first set of pins and enables the second set of pins when transferring a second set of signals in a second mode via the second set of pins. The control unit transfers a clock signal of the second set of signals by differential signaling in the second mode via a clock pin of the second set of pins. A signal transfer in the second mode is at a greater speed than a signal transfer in the first mode.
