Abstract: Systems and methods for selecting an optimal error recovery procedure for correcting a read error in a solid-state drive are provided. A machine learning model is trained to forecast which error recovery procedure of a plurality of error recovery procedures is most likely to achieve a predetermined goal given a state of a solid-state drive. The predetermined goal is based on at least one of a read latency and a failure rate of the solid-state drive. A current state of the solid-state drive is determined. An error recovery procedure is selected from among the plurality of error recovery procedures by inputting the current state of the solid-state drive into the trained machine learning model, thereby triggering the trained machine learning model to output the selected error recovery procedure. The selected error recovery procedure is executed to recover data from the solid-state drive.

Abstract: The present disclosure describes apparatuses and methods for artificial intelligence-enabled management of storage media. In some aspects, a media access manager of a storage media system receives, from a host system, host input/output commands (I/Os) for access to storage media of the storage media system. The media access manager provides information describing the host I/Os to an artificial intelligence engine and receives, from the artificial intelligence engine, a prediction of host system behavior with respect to subsequent access of the storage media. The media access manager then schedules, based on the prediction of host system behavior, the host I/Os for access to the storage media of the storage system. By so doing, the host I/Os may be scheduled to optimize host system access of the storage media, such as to avoid conflict with internal I/Os of the storage system or preempt various thresholds based on upcoming idle time.

Abstract: Systems and methods for decoding a product code is provided. The system comprises a media, a first buffer, a second buffer, and a decoder. The media stores a plurality of codewords of a first code of the product code. The first buffer temporarily stores at least one codeword that has failed to be decoded. The second buffer temporarily stores soft information to be used in decoding. The decoder is configured to decode the plurality of codewords, determine if a first count of the at least one failed codeword exceeds a designed maximum number of codewords recoverable using the decoding method. In response to determining that the first count does not exceed the predefined threshold, the decoder iteratively process each failed codeword of the at least one failed codeword with the soft information, and attempt to decode at least one of each failed codeword that has been iteratively processed.

Abstract: System and methods described herein includes a method for iterative decoding. The method includes instantiating an iterative decoding procedure to decode a codeword. At each iteration of the iterative decoding procedure, the method further includes retrieving information relating to a plurality of current decoding variables at a current iteration, determining a first current decoding variable to be skipped for the current iteration based on the information, and processing a second decoding variable without processing the first decoding variable to update related decoding variables from the plurality of current decoding variables.

Abstract: A decoding method decodes data iteratively according to a first rule, measures at a selected iteration at least one performance criterion of the decoding of data according to the first rule, performs at the selected iteration a comparison of the at least one performance criterion to a threshold, when the comparison yields a first result relative to the threshold, continues decoding according to the first rule, and when the comparison yields a second result relative to the threshold, continues decoding according to a further rule. Decoding apparatus operates according to the method. The decoding according to the first rule, the measuring at least one performance criterion at the selected iteration, the performing the comparison at the selected iteration, and the continuing decoding according to the first or further rule, may be repeated until the comparison yields a predetermined result. Repeating may be stopped after a predetermined maximum number of iterations.

Abstract: A system including a receiving module to receive data from cells of memory, each cell storing multiple bits, each bit corresponding to a different type of page of the memory, the bits stored in a cell denoting a state of the cell, and the data including bits from a page of the memory or states of cells along a word line of the memory. A processor generates a reliability indication for a first portion of the data corresponding to a first cell based on the first portion of the data and one or more second portions of the data corresponding to one or more of the cells that are adjacent to the first cell. A decoder decodes the first portion of the data based on the first portion of the data and the reliability indication for the first portion of the data.
