Abstract

See full text

Apparatuses, systems, methods, and computer program products are disclosed for redundancy mapping. A controller is configured to determine that one or more defects affect a subset of a first group of cells and a subset of a second group of cells of a non-volatile memory medium. A non-volatile memory medium may include a plurality of groups of cells, and redundant groups of cells may be available for replacing defective groups of cells. A controller is configured to store a mapping between affected subsets of first and second groups of cells and a redundant group of cells for a non-volatile memory medium. A controller is configured to read data for a first group and/or second group of cells by referencing a mapping and using a redundant group of cells.
