Abstract: A portable storage device includes a flash memory component, a flash memory interface coupled with the flash memory component, a host access interface coupled with the flash memory interface, and a control unit coupled between the flash memory interface and the host access interface to fetch a communication protocol of the host via the host access interface and adjust operation modes of the flash memory interface. If the transmission bandwidth of the host is no smaller than a set transmission bandwidth of the flash memory interface, the control unit controls the flash memory interface to work at a first operation mode. If the transmission bandwidth is smaller than the set transmission bandwidth, the control unit controls the flash memory interface to work at a second operation mode. The transmission bandwidth of the first operation mode is bigger than that of the second operation mode.

Abstract: An electronic storage device includes a first memory segment having at least one source block to store information, a second memory segment having at least one backup block corresponding to the source block to make a backup of the information in a LSB memory page of the source block and a control unit connecting with said first memory segment and second memory segment. The control unit reads/writes the first memory segment and second memory segment through two different signal channels respectively. The information can be simultaneously written into the first and second memory segment to get a backup of the information so that the information can be stored safely. The control unit recycles the backup block of the second memory segment not only after the source block of the first memory segment entirely finishes writing the information but also after the source block is erased up in order to release the storage space of the backup block.
