Abstract: The present invention discloses a method for processing data of a flash memory by differentiating levels, which includes steps of separating the communication between a host and a flash memory by a high-level translation layer (HTL) and a low-level abstraction layer (LAL). The HTL receives commands and logical addresses from the host and translates the received logical addresses to the physical addresses of the flash memory. The LAL executes data processing to the corresponding memory cells according to the commands and the physical addresses from the HTL. Since the LAL is disposed between the HTL and the flash memory, the HTL is irrelevant to the structure of the flash memory, and does not have to re-designed with the flash memory which is replaced with another new flash memory.

Abstract: The present invention discloses a switching interface method for multi-interface storage device having a transmission interfaces and a predetermining list that stores different priority weights for the transmission interfaces. When the storage device connects to a computer, the switching interface method is executed and one of the transmission interfaces is selected to communicate with the computer according to the priority weight in sequence. In addition, a user's interface is also provided for the user, and the user can switch other transmission interface of the multi-interface storage device to link to the computer. Therefore, the multi-interface storage device may link to most of the computers and successfully communicate with the computer.
