  • Publication number: 20240118821
    Abstract: A data storage device processes a mixed workload including a plurality of superblocks to be written to and read from a plurality of memory dies, where each of the plurality of superblocks to be apportioned among the plurality of memory dies. The data storage device writes a first data stripe associated with a first superblock to the plurality of memory dies according to a sequential write pattern, and reads the first data stripe associated with the first superblock from the plurality of memory dies according to a sequential read pattern. The sequential write pattern causes the controller to write to the plurality of memory dies in a first order of memory dies. The sequential read pattern causes the controller to read from the plurality of memory dies in a second order of memory dies different from the first order of memory dies, thereby reducing read collisions.

  • Publication number: 20230058632
    Abstract: Particular data is selected from a members-based dataset to provide a resultant training corpus. A first neural network receives that training corpus and generates a first trained machine learning model. That first trained machine learning model can predict member engagement score values for each of a plurality of candidate variable values. The aforementioned training corpus can also be provided to a second neural network to generate a second trained machine learning model. That second trained machine learning model can then be used to predict member engagement score values for each of a plurality of initial-state variable values. The aforementioned member engagement score values for each of the plurality of candidate variable values can then be consolidated with the member engagement score values for each of a plurality of initial-state variable values to thereby provide resultant consolidated member engagement score values.

  • Patent number: 11435908
    Abstract: Command scheduling for die sets of non-volatile memory may be performed based on command states of the die sets. Upon receiving an erase command to erase data stored in a first block set of non-volatile memory, a command state of the first die set of the non-volatile memory is determined, where the first die set contains the first block set. If the first die set is determined to be in a pending command state, the erase command is queued in a wait queue. If the first die set is determined to be in an idle command state, the erase command is scheduled to erase the data stored in the first block set.
