Computer terminals, which are widely used with the development of information and communication technology, may lose important data due to hardware or software errors, and use data storage devices such as hard disks, magnetic tapes, or optical disks. You are performing a backup operation.

As a storage device for such a backup, an optical disc such as a CD + ROM is widely used, which is slower in access speed than a hard disk but can be used to store a large amount of data at a low price. However, CD + ROM has a disadvantage in that once recorded and stored, there is a limit in erasing or recording again. Moreover, CD + ROM is inconvenient when moving due to its large volume, and there is a disadvantage in stability because data is damaged by dust or magnetic field during movement.

In order to overcome this problem, a USB device has been developed that enables storage and movement of large amounts of data by storing data in a memory through a USB interface and providing the data to a host system when using the stored data. Conventionally, USB devices are largely divided into USB memory and USB connector. The USB memory stores data through the USB connector, which serves as an interface for transferring data.

Such USB devices are used for data backup and data movement means of host systems such as PCs, laptops, MP3s, digital cameras, and the like. Most of them are provided with a receptacle, such a receptacle is a thin card type that is easily removable, such as MMC (Multi Media Card), SMC, DS, Compact Flash (CF), MS (Memory Stick), MD. In general, a data transmission method using a USB socket of a host system is generally used.

Universally used USB devices can be used in the fields of USB authentication keys for storing certificates, digital data storage such as multimedia, storage of personal credit information, e-mail authentication, login and access control in web access. .
