    Abstract: Data management logic allocates a portion such as a single plane of a respective multi-plane non-volatile memory device to store parity information for corresponding data striped across multiple planes of multiple non-volatile memory devices. According to one configuration, the data management logic as discussed herein generates parity data based on (a data stripe of) non-parity data stored in multiple planes of multiple different memory devices. The data management logic stores the parity data in the storage plane allocated to store the parity information. Additional configurations include: reserving a parity block amongst multiple non-parity data blocks to store parity data and reserving a parity page amongst multiple non-parity data pages to store parity data.

    Abstract: Provided are an apparatus, system, and method for performing an error recovery operation with respect to a read of a block of memory cells in a storage device. A current iteration of a decoding operation is performed by applying at least one reference voltage for the current iteration to a block of the memory cells in the storage device to determine current read values in response to applying the reference voltage. A symbol is generated for each of the read memory cells by combining the determined current read value with at least one value saved during the previous iteration. The symbols are used to determine bit reliability metrics for the block of memory cells. The bit reliability metrics are decoded. In response to the decoding failing, an additional iteration of the decoding operation is performed.
