ABSTRACT:
A double interface SD flash memory card includes a SD flash memory card and a USB adaptor. The SD flash memory card has a standard SD card interface and a circuit board, which has a microprocessor and flash memories. The USB adapter has at least a SD interface socket and a USB plug. The SD interface socket can be inserted with a SD flash memory card and the USB plug can be connected to other information devices. The double interface SD flash memory card includes a SD bus interface circuit for the SD flash card, a USB bus interface circuit for a system end, and an interface detection and switching circuit detect if there is an initialized signal from the system interface and switch to the SD bus interface circuit or the USB bus interface circuit based on result of the detection. The microprocessor can detect, identify, and support connecting signal of SD interface or USB interface automatically. When a signal is sent from the SD card interface or the USB card interface, the microprocessor will switch the circuit and relevant electronic elements in the circuit board to support the SD card or the USB card to access the data in the flash memories in the card.
