  • Devices, methods, and computer readable media for control page flush handling
    Patent number: 12254210
    Abstract: Embodiments herein provide a data storage device including a non-volatile memory, a second memory, and a controller coupled to the non-volatile memory and the second memory. The second memory is configured to store a plurality of delta queues. Each of the plurality of delta queues includes delta queue entries. The delta queue entries are grouped into one or more logical-to-physical (L2P) pages. Each of the one or more L2P pages is associated with a plurality of logical flash management units (LFMUs) corresponding to a plurality of physical addresses in the non-volatile memory. The controller is configured to determine that a delta queue flush is required. In response to determining that the delta queue flush is required, the controller selects one of the plurality of delta queues to flush, and flushes the one or more L2P pages stored in the one of the plurality of delta queues to the non-volatile memory.
