    • A method includes storing data encoded with an ECC in a group of memory cells by writing respective storage values to the memory cells. Multiple sets of readout results are read from the memory cells by comparing the storage values to one or more threshold combinations, each including multiple read thresholds. A plurality of partial syndromes of the ECC is computed, each partial syndrome computed over the readout results that were read using a respective threshold combination. A respective syndrome is calculated for each threshold combination, in at least a subset of all possible threshold combinations, based on one or more of the partial syndromes associated with that threshold combination. A preferred threshold combination is selected, from among the threshold combinations, for which a weight of the respective syndrome is minimal, by processing less than all the partial syndromes associated with all the possible threshold combinations.
    • 一种方法包括通过将相应的存储值写入存储器单元来将通过ECC编码的数据存储在一组存储器单元中。 通过将存储值与一个或多个阈值组合进行比较,每组包括多个读取阈值,从存储器单元读取多组读出结果。 计算出ECC的多个部分综合征,使用相应的阈值组合读取的读出结果计算每个部分校正子。 基于与该阈值组合相关联的一个或多个部分综合征,在所有可能的阈值组合的至少一个子集中针对每个阈值组合计算相应的综合征。 通过处理小于与所有可能的阈值组合相关联的所有部分综合征,从相应综合征的权重最小的阈值组合中选择优选阈值组合。
