  • Patent number: 11204697
    Abstract: Embodiments of the present disclosure provide a memory-efficient mechanism for identifying memory blocks with a low wear count. More particularly, embodiments of the present disclosure provide a mechanism for identifying a memory block whose wear count is within the bottom p % of all wear counts associated with memory blocks in a storage system. If a memory controller performs the garbage collection operation on a memory block whose wear count is within the bottom p % of all wear counts, then the memory controller is expected to utilize the remaining memory blocks (e.g., memory blocks whose wear count is within the upper (100-p) % of all wear counts) efficiently and level the wear count of at least the remaining memory blocks.
    Type: Grant

    Date of Patent: December 21, 2021
    Assignee: Western Digital Technologies, Inc.

If a memory controller performs the garbage collection operation on a memory block whose wear count is within the bottom p % of all wear counts, then the memory controller is expected to utilize the remaining memory blocks (e.g., memory blocks whose wear count is within the upper (100?p) % of all wear counts) efficiently and level the wear count of at least the remaining memory blocks.

  • Patent number: 10019166
    Abstract: Embodiments of the present disclosure provide a memory-efficient mechanism for identifying memory blocks with a low wear count. More particularly, embodiments of the present disclosure provide a mechanism for identifying a memory block whose wear count is within the bottom p % of all wear counts associated with memory blocks in a storage system. If a memory controller always performs the garbage collection operation on a memory block whose wear count is within the bottom p % of all wear counts, then the memory controller is expected to utilize the remaining memory blocks (e.g., memory blocks whose wear count is within the upper (100-p) % of all wear counts) efficiently and level the wear count of at least the remaining memory blocks.
