Embodiment
Now cooperate and graphic the utility model preferred embodiment is described in detail as follows.
As shown in Figure 3, it is the block scheme of the utility model embodiment.Comprising:
One USB host 10; One virtual memory device 40.
Wherein, this virtual memory device 40 further comprises at least one universal serial bus device controller 41, a plurality of storage device 42, a processor 44 and a virtual Storage Media 43.This storage device 42 is for true storage device and more comprise a Storage Media controller 421 and a Storage Media 422.
This universal serial bus device controller 41 electrically connects this USB host 10; This Storage Media 422 electrically connects this Storage Media controller 421; This processor 44 electrically connects this universal serial bus device controller 41, this Storage Media controller 421 and this virtual Storage Media 43.
This processor 44 can be detected corresponding to the signal of choosing of this storage device 42 respectively and specify this storage device 42 to choose, and should virtual Storage Media 43 contiguous memory spaces and temporary these storage device 42 data of appointment for being disposed in this virtual memory device 40.
