Abstract
A method and associated memory system for reading data from a memory. The method reads data from a memory group of the memory; calculates a group divergence metric for read biases used to read the data from the memory group; when the group divergence metric meets a threshold, partitions the memory group into a first sub-group and a second sub-group, wherein the first sub-group has a lower error rate than the second sub-group; reads data from the first and second sub-groups; calculates respective sub-group divergence metrics for the read biases used to read the data from the first and second sub-groups; and when one of the sub-group divergence metrics meets the threshold, partitions the one sub-group of the first and second sub-groups which met the threshold into a third sub-group.
