Abstract:
1. A method for generating a physical identifier in a storage device that includes a plurality of storage regions, the method comprising: Determining, by a host device, a number of reference storage regions for uniquely identifying the storage device; comparing, by the host device, the number of reference storage regions to a threshold; generating, by the host device, auxiliary storage regions for uniquely identifying the storage device, such that a number of the auxiliary storage regions is determined based on a difference between a function value of the number of reference storage regions and the threshold; generating, by the host device, location distribution information of the reference storage regions and auxiliary storage regions; and storing, by the host device, the location distribution information in the storage device, wherein each of the reference storage regions and auxiliary storage regions is a block of memory in the storage device.
