Abstract

The utility model discloses a USB storage module encapsulated integratively, comprising a memory chip, a processor and a USB interface connected in sequence, wherein the memory chip, the processor and the USB interface are encapsulated integratively to compose a USB storage module. When the USB storage module of the utility model is encapsulated integratively, the built-in chip is integrated in integratively, the size of the USB storage module is small, and memory capacity is set in 1 GB-16 GB, meanwhile the storage module has a storage interface, which can be assembled into a U disk with cases in a plurality of types.

Description

The USB memory module of one encapsulation

Technical field:

The utility model relates to a kind of one encapsulation storage module of the ROHS of meeting standard, in particular tool USB interface and the big removable data memory module of memory capacity used of USB flash disk.

Background technology:

Show that according to the correlation study report global sales of USB flash disk (the tool USB interface is data storage device movably) has surpassed the 50KK/ month at present.Along with the decline of technical scheme threshold, and DRAM price continue drop, the market demand of USB flash disk and growth will increase severely with day.But the USB flash disk of prior art still has the following disadvantages, wherein too the memory capacity of complexity and memory module is lower for the linkage editor of the memory module of USB flash disk, moreover be that the monnolithic case size of USB flash disk was bigger after the size of the memory module used according to the prior art USB flash disk was produced the finished product USB flash disk.Above-mentioned deficiency all is a urgent problem in the industry.

The utility model content:

At the deficiencies in the prior art, the utility model provides that a kind of size is little, memory capacity is high, and the one of the USB flash disk shell of arbitrarily arranging in pairs or groups encapsulation USB storage module.

The utility model is implemented by the following technical programs:

The USB memory module of one encapsulation is characterized in that: comprise the storage chip that is linked in sequence, processor and USB interface, storage chip, processor and the encapsulation of USB interface one constitute the USB memory module.

Described processor comprises single-chip microcomputer and the data/address bus of mating with single-chip microcomputer, is connected with program read-only memory, program random access memory, data with note storer, register in the periphery of single-chip microcomputer through data/address bus.

Described USB memory module length is respectively 11.3mm, 24.8mm, 1.4mm.

The beneficial effect of the USB memory module of the utility model one encapsulation is: chip height built-in during the encapsulation of USB memory module one is integrated, USB memory module size is less, and memory capacity can be arranged on 1GB-16GB, this memory module tool USB interface simultaneously, various types of shells of can arranging in pairs or groups are assembled into USB flash disk.Bring convenience for production and use.

Description of drawings:

Fig. 1 is an one-piece construction synoptic diagram of the present utility model;

Fig. 2 is the distribution schematic diagrams of each parts on the USB memory module;

Fig. 3 is the schematic diagram of the USB memory module of the utility model one encapsulation.

Embodiment:

Below in conjunction with accompanying drawing the utility model is described further:

As shown in Figure 1: the USB memory module 10 of the utility model one encapsulation, mainly form by storage chip, processor and USB joint, appropriate location on the USB memory module 10 is distributed with metal haptic element 1, metal haptic element 2, metal haptic element 3, the metal haptic element 4 that is electrically connected with usb host, also is provided with on the USB memory module 10 with external pilot lamp and is electrically connected positive and negative contact.

With after being linked in sequence of storage chip, the components and parts of forming processor and USB interface, one is encapsulated in the back USB joint space that length is 11.3 * 24.8 * 1.4mm in and reveals the outside surface that is located at the USB memory module that one encapsulates the utility model according to position shown in Figure 2.

The schematic diagram of USB memory module for the one encapsulation shown in Figure 3, processor in the present embodiment comprises a slice 8051 single-chip microcomputers and the data/address bus of mating with single-chip microcomputer, is connected with program read-only memory, program random access memory, data with note storer, register in the periphery of single-chip microcomputer through data/address bus.Single-chip microcomputer is in order to cooperate the visit of chip microcontroller to storage chip, the function of complete realization USB memory module with program read-only memory, program random access memory, data with the purpose of note storer, register communication.

The utility model can be selected for use and compatible USB2.0 and USB1.1 port, with the USB memory module of one encapsulation be linked into corresponding model main frame after, the work of USB memory module.8051 single-chip microcomputers are visited storage chip through the flash memory steering logic in the mode of direct memory access.Continue the visit storage chip as after finding the error detection sign indicating number, correcting, realize USB memory module function with this.Certainly, the working method of above-mentioned processor is a kind of concrete mode of the present utility model, only is used for the function that illustrates that more easily this use is novel, does not come protection domain as present patent application with this.

Utilize the USB memory module of the utility model one encapsulation shell that various styles are installed of arranging in pairs or groups simply and easily to be assembled into USB flash disk, give and produce and use brings convenience.
