  • Patent number: 10956263
    Abstract: Memory systems, controllers, decoders and methods execute decoding with a mufti-level interference correction scheme. A decoder performs first soft decoding to generate log likelihood ratio (LLR) values of a select bit and bits of memory cells neighboring a memory cell of the select bit. A quantizer obtains an estimated LLR value of the select bit based on the LLR values of the select bit and the bits of the memory cells neighboring the memory cell of the select bit, when the first soft decoding fails. The decoder performs second soft decoding using the estimated LLR value when the first soft decoding fails, and performs third soft decoding using information obtained from application of a deep learning model to provide a more accurate estimate of the LLR value of the select bit when the second soft decoding fails.

  • Patent number: 10949113
    Abstract: Techniques for profiling storage blocks in non-transitory memory (e.g., flash memory dies) to determine their retention capability, and assigning them with labels based on retention, are described. A superblock (SB) can be formed from physical blocks with the same labels located in different dies. The disclosed system and methods improve storage efficiency when the update frequency of stored data is non-uniform, as is typically the case. Moreover, the disclosed embodiments improve the reliability of solid state drives (SSDs), as well as reduce data refresh frequency and write amplification due to periodic refresh. A storage system can comprise a controller configured to obtain expected retention times for a plurality of storage blocks.

  • Patent number: 10910002
    Abstract: One or more write efficiency metrics are determined. The one or more write efficiency metrics are associated with a tape storage drive while the tape storage drive is operating on one or more tape storage media cartridges to write data sets to the one or more tape storage media cartridges. It is predicted whether the tape storage drive would be able to write an entire set of data sets to a current tape storage media cartridge based on the one or more write efficiency metrics. It is determined whether a different tape storage drive is to be utilized to complete writing of the entire set of data sets to the current tape storage media cartridge based on the prediction.

  • Patent number: 10901656
    Abstract: Soft read suspend schemes for a memory system reduce overall command latency and improve QoS of the memory system, which includes a memory device and a memory controller. The memory controller controls the memory device to perform, in response to a command, a hard read to generate hard information for hard decoding, and predict whether soft decoding of the data is to be performed, and if so, how many soft reads are to be performed. When hard decoding fails and soft decoding and at least one soft read is to be performed, the memory device is controlled to perform an initial soft read to generate soft information for soft decoding, predict whether, and if so, how many, subsequent soft reads are to be performed, and determine whether to perform a first subsequent soft read on the data based on the prediction.
