ABSTRACT:
The present invention discloses a virtual integrated drive electronics (IDE) card reader with a peripheral component interconnect express (PCI Express). The card reader includes a microcontroller connected to a PCI Express connecting interface and a memory card connecting interface separately. The microcontroller includes a memory card interface, a PCI Express interface, and a virtual IDE module. The virtual IDE module includes a IDE host and a IDE device. If the host sends an instruction for storing or reading data to a memory card connected to the card reader, the instruction will be sent to and executed in the virtual IDE module. The data in the memory card can be transmitted at a transmission rate up to the standard of an IDE device, and the host will consider the card reader as an IDE device instead of a PCI Express device only.
