  • Patent number: 11483014
    Abstract: A controller of a memory system performs a soft decoding without additional reads. The controller applies each of read voltages to cells to obtain a corresponding cell count and corresponding data, stores the obtained data, and processes the stored data. The controller determines a set of parameters, based on (i) the read voltages, (ii) cell counts corresponding to the read voltages and (iii) a non-negative regularization parameter. The controller estimates an optimal read voltage based on the set of parameters, generates log-likelihood ratio (LLR) values using the processed data and the optimal read voltage and performs soft decoding using the LLR values.

  • Patent number: 11265021
    Abstract: A memory controller performs an error recovery operation. The controller performs a read operation on a select block using a select read level; decodes data associated with the read operation to generate a syndrome value; determines whether to stop, before a maximum number of iterations, the read operation and the decoding at the select read level, using the syndrome value; when it is determined to stop the read operation and the decoding at the select read level, selects a next read level in a sequence of read levels; and uses the next read level for a subsequent read operation.
