Abstract: Apparatuses, systems, methods, and computer program products are disclosed for data register copying for a non-volatile storage array. An apparatus may include an array of non-volatile storage cells. A set of write buffer data registers may be configured to store target data for a program operation for an array. Write buffer data registers may communicate target data to corresponding columns of an array. A set of shadow data registers may be configured to receive target data from peripheral circuitry for an array. A portion of target data received by a shadow data register may be copied to a corresponding write buffer data register while the shadow data register receives the portion of the target data.

Abstract: 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.
