Abstract
A virtual USB flash memory storage device with a PCI express bus is disclosed. There is a micro controller in the storage device. The micro controller is connected to the flash memory and the interface connector of the PCI express bus, respectively. The micro controller has a flash memory interface, a PCI express bus interface, and a virtual USB interface module. The virtual USB interface module comprises a virtual control terminal and a virtual device terminal of the USB interface. When a computer host issues a USB interface command through its PCI express bus to store/read the information in the storage device, the command is transmitted to the virtual USB interface module and is processed in the virtual USB interface module. The data processing operation for the stored/read information is processed in the flash memory via the flash memory interface. The information in the storage device is transmitted at a speed as high as the transmission speed of the PCI express bus, so the computer host looks the storage device as a USB interface device but not simply a PCI express bus interface device.
