Problems solved by technology

[0002] At present, in mobile storage devices, there is a common purpose that cannot be truly mobile for storage. Most of them are inconvenient to carry because of their large size, such as external hard disks, external recorders, ZIP, MO, etc. These devices can provide large-capacity storage but lack of mobility
As a portable memory, for example, a floppy disk, not only the dedicated drive takes up a large volume, but also consumes a lot of energy and noise, and because the floppy drive runs slowly, the storage space is small, and the reliability of data storage is low. In addition to its characteristics, because the floppy disk itself is a portable product, it is prone to physical damage during use, so the existing memory is already insufficient in practicality, but because of its low cost, there has been no high-efficiency and low-cost invention that can replace it. The advent of floppy drives and floppy disks also survived

Embodiment Construction

[0034] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0035] As shown in Figures 1, 2, and 3, the present invention is a portable read-write memory with a USB interface, which includes an external housing and a control circuit in the housing, wherein the control circuit includes a USB interface, a flash memory, CPU, register; where CPU completes address gating and digital-to-analog conversion, and its port is connected to USB, flash memory, and register.

[0036] A window 2 is provided on the housing 1, and a read-write control switch 3 is arranged in the window 2. One end of the switch control end is connected to the read-write control line of the CPU port of the control circuit, and one end is grounded. The manipulating part of the read-write control switch 3 is arranged on the outer side of the casing 1 . And the read-write control switch 3 is a slide switch that can be moved along t...

Abstract

There is a portable accessing memorizer which has a USB interface, it includes the outer shell and the control circuit in the shell, the control circuit includes USB interface, flash memory, CPU buffer memory; The CPU accomplishes address selecting and D / A conversion, its port connects to USB, flash mmeory, buffer memory. The CPU port also connects to infrared module or radio frequency identification module which has a inductive antenna. The invention has a big storage quantity, high reliability, it is portable, it not only can integrate radio frequency identification instruments or wireless receiving groupware, it is used as the communication interface of personal computer, but also can be a identificatino instrument of personal identity. On the other hand, it can encrypt the data perfectly and manage the accessing of data.
