Problems solved by technology
[0004] For example, the currently widely used USB protocol for data transmission and flash memory (FLASHMemory) as a storage medium for mobile storage devices, after the introduction of USB2.0, the speed between the host system and the control module of the storage device can reach 480Mbps, while Due to the limitations of the inherent read and write characteristics of flash media, the data operation speed for 8bit flash media can only reach 160bps at the highest, and the control module of the above-mentioned mobile storage device currently uses a single-channel control method for flash media, which can only operate on one piece at a time. For flash media reading and writing, if it is a single-chip 8bit flash media, the maximum transmission speed in the laboratory is: read data 80bps, write speed 64bps; if it is a single-chip 16bit flash medium, the maximum transmission speed in the laboratory is: read data 160bps, write speed 128bps Obviously, the data access speed of the control module in this control mode to the flash memory medium is much lower than the data transmission speed between the host system and the control module, and the high data transmission rate between the host system and the control module cannot be fully utilized. Thus limiting the data access speed between the host system and the storage medium

The invention is a mobile storage device and method for raising data access speed, and the mobile storage device can make data transmission with a host machine system and comprises a control module able to make data transmission with the host machine system through communication protocol and a data storage module, characterized in that the said storage module can comprise one or many basic storage modules, and that the control module can make data access operation on the said basic storage modules. The invention alternately makes access operation on the basic storage units composed of the said one or many basic storage modules with data packet as a unit for the data coming from the host machine system, and then largely raising the speed of reading and writing the storage modules.
Description
technical field [0001] The invention relates to storage control technology, in particular to a mobile storage device and method for improving data access speed. Background technique [0002] With the popularization of personal computers, various digital products are increasingly closely related to people's work and life, and the subsequent processing and carrying of a large amount of data has become an urgent problem to be solved. Therefore, various mobile storage devices emerge in endlessly, and semiconductor storage devices Because of the advantages of small size, large capacity, high-speed access, easy to carry, stable performance, and not easy to damage, it has been more and more widely used. [0003] The current semiconductor storage device is composed of a control module and a storage medium. The host system performs data read and write operations on the storage medium through the control module. The control module and the host system can communicate through various da...
