Adaptive LLR based on syndrome weight

摘要

Systems, methods and/or devices that enhance the reliability with which data can be stored in and read from a memory utilize an error indicator to adaptively determine the soft information values used for decoding. For example, in some implementations, the method includes selecting a first set of one or more soft information values and receiving a read data command. The method further includes responding to the read data command by initiating performance of a data access operation to access data in a storage medium, the data access operation producing a syndrome weight; determining a first indicator based at least in part on the syndrome weight; based on the first indicator, selecting a second set of one or more soft information values; and decoding data obtained from the data access operation using the second set of one or more soft information values to produce a result.

1. A method of decoding data, the method comprising:
selecting a first set of one or more soft information values; receiving a read data command; and responding to the read data command by:
initiating performance of a data access operation to access data in a storage medium, the data access operation producing a syndrome weight;determining a first indicator based at least in part on the syndrome weight;based on the first indicator, selecting a second set of one or more soft information values; anddecoding data obtained from the data access operation using the second set of one or more soft information values to produce a result.
