Abstract
This invention relates to a flash memory device of USB flash memory disc, which belongs to the technique field of flash memory disc and USB interface. Nowadays, USB flash memory disc is widely used and the capacity of the disc becomes larger and larger such as 128MB, 256MB, 1GB,5GB,. The function and usage scope also becomes larger and larger. There is only one flash memory device to store data in the USB flash memory disc and only one USB interface, so the hardware can not be cut into several small hardware to store the different data and is easy to be attacked by virus with little security and speed. More than one flash memory devices, USB interfaces, and flash memory connected switches are installed in one USB flash memory disc.
Description
(1) technical field:
The present invention relates to many flash memory devices of USB flash drive, belong to flash disk and USB interface technical field.
(2) background technology:
USB flash drive is used generally at present, and capacity is increasing as 128MB, 512MB, and 1GB, 5GB, the function of use and scope are also increasing, deposit computer information, sound, photo, booting computer slowly replaces hard disk, CD.A present USB flash drive has only a flash memory device to deposit data, and a USB interface can't be cut several small harddisks as hard disk and separately be deposited data with different, and susceptible viral is attacked, and security is not enough, and transmission speed is subjected to the restriction of an interface.Other devices that have flash memory capability now also have same problem as MMC, SD card, miniSD, memory stick (comprising PRO), memory stick Duo (comprising PRO).Especially now data is increasing, deposits TV, picture, and music, data such as individual classified papers more seem dangerous, transmission speed is too slow.
(3) summary of the invention:
Can't cut for solving existing USB flash drive, cause susceptible viral to attack, data is deposited dangerous, slow shortcoming.The present invention installs more than one flash memory device a USB flash drive, an above USB interface, an above flash memory connects change-over switch, can separately deposit data with different a USB flash drive, a plurality of data transmissions switch different flash memories and deposit data with different simultaneously.The present invention has data and separately deposits safely, and simultaneously data transmission speed is fast, the advantage of cost saving
The present invention finishes by following technical measures:
The present invention installs an above flash memory device, an above USB interface a USB flash drive.
(4) description of drawings:
Below in conjunction with accompanying drawing structure of the present invention is described further:
Fig. 1 is the enforceable structural drawing of many flash memory devices of USB flash drive of the present invention.Wherein: 1 USB flash drive, 2 flash memory devices, 3 flash memories connect change-over switch, 4 USB interface.
(5) embodiment:
Embodiment: structure of the present invention as shown in Figure 1, USB flash drive 1, flash memory device 2, flash memory connect change-over switch 3, USB interface 4.There is flash memory device 2 USB flash drive 1 the inside, and flash memory connects change-over switch 3, USB interface 4.Flash memory device 2 connects flash memory and connects change-over switch 3, and flash memory connects change-over switch 3 and connects USB interface 4.Flash memory device 2 can be a different capabilities.USB interface 4 can be the interface that various shapes connects different product, wired connection, wireless connections interface.
In sum, more than be part embodiment of the present invention, but be not in order to restriction the present invention.All according to creative spirit of the present invention and feature, pattern, any device that has the flash memory device of USB interface and have a flash memory capability install that an above flash memory device changes a little all should be in protection scope of the present invention the inside.This project is consulted the patent registration of 2001.1 to 2005.1.30 Department of Intellectual Property, do not have identical, similar patent.
