  • 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.

  • Patent number: 10877840
    Abstract: A storage system includes memory cells arranged in an array and a memory controller coupled to the memory cells for controlling operations of the memory cells. The memory controller is configured to perform a read operation in response to a read command from a host, perform a first soft decoding of data from the read operation using existing LLR (log likelihood ratio) values stored in the memory controller, update existing LLR values using LLR values from neighboring memory cells and existing weight coefficients that account for influence from the neighboring memory cells. The memory controller is also configured to perform a second soft decoding using the updated LLR values. If the second soft decoding is successful, the memory controller performs a recursive update of weight coefficients to reflect updated influence from neighboring memory cells and stores the updated weight coefficient in the memory controller for use in further decoding.

  • Patent number: 10847231
    Abstract: Adaptive read-threshold schemes for a memory system determine read-threshold with the lowest BER/UECC failure-rates while continuing to serve the host-reads with the required QoS. When it is determined that the QoS or other quality metric is not met for a particular read-threshold, which may be an initial, default, read-threshold, the performance of other read-thresholds are estimated. These estimates may then be used to determine an optimal read-threshold. During the iterative process, selection variables, e.g., how many times, and for which read commands, to use each of the non-default read-thresholds in future read-attempts may be determined on-the-fly.
