Abstract
A storage device includes a controller and a memory. A method of storage space management for the storage device is executed to perform steps as below. The controller calculates an expectedly used capacity and an effective capacity of the memory. The controller determines whether blocks of the memory include one or more blocks that are non-bad blocks and are prohibited from reading/writing. When the one or more blocks are determined to be non-bad blocks and to be prohibited from reading/writing, the controller marks each of the one or more blocks as a restricted block other than a bad block, thereby maintaining the effective capacity to be unchanged. The controller compares difference of the effective capacity and a total capacity of the one or more blocks that are marked as the restricted block to the expectedly used capacity to determine whether to prohibit programming to the memory.
