The memory chip is connected with the USB master control chip, and the USB interfaces are respectively connected with the USB master control chip. The USB flash disk is provided with the various USB interfaces, accordingly, a USB conversion line is omitted, and the USB flash disk is quite convenient to use.
Description
Technical field
The utility model relates to a kind of memory device, particularly a kind of USB flash disk.
Background technology
USB flash disk of the prior art only has a kind of USB interface usually.The user can insert USB flash disk easily in the standard USB interface in the apparatus such as computer by this USB interface and go.Yet, common Application standard USB interface not in the present various portable sets (such as mobile phone, MP3, digital camera etc.), but use less miniUSB interface or the microUSB interface of size.Therefore, USB flash disk of the prior art must pass through the USB interface conversion line, could be connected with these portable sets, therefore brings very large inconvenience to use.
The utility model content
The utility model provides a kind of USB flash disk, to solve the problem that can not easily USB flash disk be connected with portable set in the prior art.
For addressing the above problem, as an aspect of the present utility model, provide a kind of USB flash disk, comprising: the USB main control chip; Storage chip is connected with the USB main control chip; At least two kinds of USB interface are connected with the USB main control chip respectively.
Further, USB interface comprises in standard USB interface, miniUSB interface and the microUSB interface at least two kinds.
Further, USB interface is two kinds, and two kinds of USB interface are respectively standard USB interface and miniUSB interface.
Further, two kinds of USB interface are separately positioned on the both sides of USB flash disk.
Further, USB interface is two kinds, and two kinds of USB interface are respectively standard USB interface and microUSB interface.
Further, two kinds of USB interface are separately positioned on the both sides of USB flash disk.
Therefore the utility model, in the process of use, no longer needs to use the USB conversion line owing to had multiple USB interface, very convenient to use.
Description of drawings
Fig. 1 schematically shows the synoptic diagram of an embodiment of the present utility model.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
USB flash disk in the utility model comprises: the USB main control chip; Storage chip is connected with the USB main control chip; At least two kinds of USB interface are connected with the USB main control chip respectively.Like this, USB flash disk just can be by different USB interface and different equipment connections, and is very convenient to use.
Preferably, USB interface comprises in standard USB interface, miniUSB interface and the microUSB interface at least two kinds.
As shown in Figure 1, in a preferred embodiment, the USB interface of the USB flash disk in the utility model is two kinds, and two kinds of USB interface are respectively standard USB interface 10 and miniUSB interface 20.Preferably, two kinds of USB interface are separately positioned on the both sides of USB flash disk.Certainly, these two kinds of USB interface also can be respectively standard USB interface and microUSB interface.
In the time USB flash disk and computer etc. need to being had the equipment connection of standard USB interface, the Application standard USB interface.When needs are connected USB flash disk with portable set, can use miniUSB interface or microUSB interface.Owing to had multiple USB interface, therefore, in the process of use, no longer need to use the USB conversion line, very convenient to use.
The above is preferred embodiment of the present utility model only, is not limited to the utility model, and for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
