    • A flash drive and method of transferring data from a system to a flash drive. The flash drive includes a casing, a plurality of flash memory devices within the casing, each of the flash memory devices having multilevel cells, an IEEE 1394 interface controller within the casing, coupled to the flash memory devices, and interfacing with the flash memory devices for interleaved multichannel access to and from at least two of the flash memory devices, and at least one IEEE 1394 interface connector projecting from the casing for interfacing the flash memory devices with a system through the controller. The method entails coupling a plurality of multilevel cell flash memory devices to a system through an IEEE 1394 interface controller and at least one IEEE 1394 interface connector, and performing interleaved multichannel access to and from at least two of the flash memory devices.
    • 闪存驱动器和将数据从系统传输到闪存驱动器的方法。 闪存驱动器包括壳体,壳体内的多个闪存器件,每个闪存器件具有多电平单元,壳体内的IEEE 1394接口控制器,耦合到闪存器件,并与闪存器件接口 用于对来自至少两个闪存器件的交织多通道访问,以及从壳体突出的至少一个IEEE 1394接口连接器,用于通过控制器将闪存器件与系统接口连接。 该方法需要通过IEEE 1394接口控制器和至少一个IEEE 1394接口连接器将多个多电平单元闪存器件耦合到系统,并且执行至少两个闪存器件的交错多通道访问。
