Abstract
An identification code generation method and a management method for a non-volatile memory, and a controller and a storage system using the same are provided, and the non-volatile memory has a plurality of physical blocks. The identification code generation method includes testing the physical blocks to obtain an availability state of the physical blocks and identifying a plurality of good physical blocks or bad physical blocks among the physical blocks according to the availability state. The identification code generation method also includes generating a memory identification code corresponding to the non-volatile memory according to the good physical blocks or the bad physical blocks. Thereby, in the present invention, a unique memory identification code is generated and is prevented from being stolen.
