    Abstract: Information associated with a neighborhood is obtained based at least in part on a source location. It is determined, based at least in part on the information associated with the determined neighborhood, whether to perform a copy back operation using a specified set of one or more read thresholds. In the event it is determined to perform the copy back operation using the specified set of read thresholds, the copy back operation is performed on the source location using the specified set of read thresholds.

    Abstract: A first bit position of a cell in solid state storage is read where a sorting bit is obtained using the read of the first bit position. A second bit position of the cell is read for a first time, including by setting a first read threshold associated with the second bit position to a first value and setting a second read threshold associated with the second bit position to a second value. The second bit position of the cell is read for a second time, including by setting the first read threshold to a third value and setting the second read threshold to a fourth value. A new value for the first read threshold and for the second read threshold is generated using the sorting bit, the first read, and the second read.

    Abstract: A victim group of one or more cells is read using a first read threshold to obtain a first raw read which includes one or more values. The victim group of cells is read using a second read threshold to obtain a second raw read which includes one or more values. A neighboring read, corresponding to a neighboring group of one or more cells associated with the victim group of cells, is obtained. A composite read is generated, including by selecting from at least the first raw read and the second raw read based at least in part on the neighboring read.

    Abstract: A value read back from storage and a set of bins are received. Each bin in the set of bins has a bin range. A bin corresponding to the read-back value is selected from the set of bins. The bin range of the selected bin is adjusted, based at least in part on the read-back value, so that the read-back value is more centered within the selected bin after adjustment.
