Abstract: A virtual universal serial bus (USB) flash memory storage device with a peripheral component interconnect (PCI) Express interface including a microcontroller connected separately to a flash memory and a PCI Express connecting interface, and the microcontroller has a flash memory interface, a PCI Express interface and a virtual USB module and the virtual USB module includes a USB host and a USB device. If a host gives a USB instruction for saving or reading to the storage device, the USB instruction will be sent to and executed by the virtual USB module and the required data processing for saving or reading will be completed through the flash memory interface and the flash memory. The data in the storage device can be transmitted with a PCI Express standard transmission rate, and the host considers the storage device as a USB device instead of a pure PCI Express device.

Abstract: A solid state disk (SSD) storage system with a parallel accessing architecture, including a SSD controller and a plurality of transmission interfaces of a predetermined bit number and bandwidth, and a solid state disk controller thereof are provided. The SD controller forms channels for transmitting control signals and data with one or more flash memories through each of the transmission interfaces. That is, independent transmission channels are constituted between the SSD controller, the transmission interfaces with multiple bits, and the flash memories. In one embodiment, the transmission interfaces are compatible with MMC 4.0 protocol or higher. Moreover, a host controls and accesses the flash memories through a SATA bus interface and the SSD controller, and uses a direct memory access (DMA) engine with a bidirectional connection port in the SSD controller to transmit data.

Abstract: The present invention discloses a virtual universal serial bus (USB) card reader with a peripheral component interconnect (PCI) Express interface. 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 USB module. The virtual USB module includes a USB host and a USB device. If a host gives an instruction to a memory card connected to the card reader for storing or reading data, the instruction will be sent to and executed by the virtual USB module. The data in the memory card can be transmitted at a transmission rate up to the USB standard, and the host will consider the card reader as a USB device instead of simply a PCI Express device.
