  • Publication number: 20250370926
    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.

  • Patent number: 12468485
    Abstract: The present disclosure discloses example memory systems and operating methods thereof, and electronic systems. An example memory system includes a memory device and a controller coupled to the memory device. The controller is configured to receive a read command from a host, access a corresponding region of the memory device according to the read command, update hotness information of the corresponding region in a hotness table, determine one or more active regions based on the hotness information of regions in the hotness table, and send mapping information corresponding to the one or more active regions to the host. The hotness information includes a number of times a region is accessed by read commands from the host. The mapping information includes a mapping relationship table from logical address to physical address.

  • Patent number: 12436879
    Abstract: In some examples of the present disclosure, a ring queue may be constructed according to a number of first logical blocks, and the number of elements of the ring queue may be the same as the number of first logical blocks. For example, a first input first output (FIFO) ring queue with a depth of M is initialized to manage the resource of the first logical block. Each element in the ring queue can store an identity of a corresponding first logical block and an allocation state of the first logical block, for example, a first element of the ring queue stores an identity (ID=1) of a first one of the first logical blocks, . . . , a M-th element stores an identity (ID=M) of a M-th one of the first logical blocks, and an initial allocation state of each first logical block may be configured as the unallocated first state.
