Abstract: The present disclosure provides a method for operating a memory system. The method includes providing a logical block management table, wherein the logical block management table includes a first sequence corresponding to identities of M first logical blocks, the identities of the M first logical blocks are constructed as a ring queue, and allocation states of the M first logical blocks are managed through the logical block management table. The method may include allocating, according to an order of the identities of the M first logical blocks in the ring queue, one first logical block whose allocation state is a first state representing an unallocated state to one second logical block among N second logical blocks. The method may include updating the allocation state of the first logical block in the logical block management table from the first state to a second state representing an allocated state.
