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