[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 160Mbps (please confirm), and the control module of the above mobile storage device currently uses a single-channel method for flash media, each time only Can read and write to a piece of flash memory media, if it is a single-chip 8bit flash memory medium, the maximum transmission speed in the laboratory is: read data 80Mbps, write speed 64Mbps; if it is a single-chip 16bit flash memory medium, the maximum transmission speed in the laboratory is: read data 160Mbps, The write speed is 128Mbps. 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 rate between the host system and the control module cannot be fully utilized. Transfer rate, which in turn limits the speed of data transfer between the host system and the storage medium

A mobile storage device and method to improve data access speed. The device can transmit data to main computer system, improve speed and comprises: control module that can take data transmission to main computer system by communication protocol, storage module with at least two data channels connected to control module; control module takes access operation for data of data package form of time sharing or simultaneity to storage module through data channel, then increases data access speed.
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...
