A bridging circuit is provided. The bridging circuit includes a USB interface, a USB host, a memory card interface, a buffer and a microprocessor controller. The USB host reads data from and outputs data to a USB device via the USB interface. The memory card interface reads data from and outputs data to a system device. The buffer stores the data from the USB host and/or the memory card interface. The microprocessor controller outputs control signals to the USB host, the buffer and the memory card interface to mediate the data transmission between the USB host, the buffer and the memory card interface.
