The present invention discloses a semiconductor storage device with host system operating function. Said device includes controller unit, semiconductor storage unit, interface unit, information prompting unit, input control unit and power supply unit. The interface unit of said invented device can be connected with diferent external equipment or host system, system software which is set in the described semiconductor storage device and has host system operating function and equipment connected for automatic detection. According to the type of connected equipment the automatic change-over can be made between host made of external equipment mode, and the correspondent function of external equipment or host system also can be executed. Said invented semiconductor device not only can be used as external mobile storage device, but also can be used as host system of other external devices, and can be used for implementing direct data exchange between said semiconductor storage device and other external device.
Description
technical field [0001] The invention relates to the field of data communication, in particular to a semiconductor storage device used in the data exchange process. Background technique [0002] With the development of communication technology and the maturity of semiconductor storage technology, the development of large-capacity data semiconductor storage technology has been driven. The Chinese patent "Flash electronic external storage method and device for data processing system" (Chinese patent number: ZL99117225 .6) A semiconductor storage method and device adapted to a USB interface and using a flash memory (Flash Memory) as a storage medium are disclosed. Products implemented according to the patented method currently have a wide range of application groups. However, this type of semiconductor storage product does not have the host function, but has been only used as an external device of the computer system for data mobile storage, and does not support direct data comm...
