Jing Nie · Journal of Hefei University of Technology · 2007
The rapid updating of the technology for mobile memory devices has brought wide application of flash disks,and the interface technology based on USB 2.0 has made the transmission speed of flash disks advance rapidly,so the exploitation of the firmware of flash disks has become a main task in flash disk researches.In this paper,the hardware structure of a flash disk is presented,and the software frame and design method of the firmware of the flash disk based on USB 2.0 are discussed in detail.The hierarchical configuration of the firmware is introduced through the example.The presented design has notable advantages in comparison with the firmware based on USB 1.1.
