An electronic device capable of accessing a memory card is provided. The electronic device includes a circuit board, a processing unit, a memory card slot, and a memory card access module. The processing unit is disposed on the circuit board. The memory card slot is disposed on the circuit board, allows the insertion of the memory card, and is coupled to the processing unit through a first signal line. The memory card access module is disposed on the circuit board for accessing the memory card. The memory card access module is coupled to the processing unit through a second signal line and coupled to the memory card slot through a third signal line and a fourth signal line. The first signal line, the second signal line, and the third signal line conform to the standard of a signal transmission interface.
