BLOCK FAMILY COMBINATION AND VOLTAGE BIN SELECTION

Abstract:

A set of two or more block families associated with a bin boundary of a first voltage bin is identified. A determination of at least a first voltage for a first block family of the plurality of block families and a second voltage for a second block family of the plurality of block families based on values of a data state metric for each of the plurality of block families. In response to a determination that a difference between the first voltage and the second voltage satisfies a block family combination criterion, the second block family is merged with the first block family.
