    摘要: In a nonvolatile memory system a Soft-Input Soft-Output (SISO) decoder corrects errors in data that is read from a memory and a statistical unit connected to the SISO decoder collects data regarding corrections. The statistical unit generates at least one output based on the collected data and at least one operating parameter of the memory is modified in response to the output.

    摘要: Data is read from a nonvolatile memory array using one or more read voltages that are adjusted during memory life. Programming target voltages and read voltages may be adjusted together over memory life to map memory states to an increasingly wide threshold window. Individual memory states are mapped to sub-ranges that are made wider, reducing errors.

    摘要: In a nonvolatile memory system, data is read from a memory array and used to obtain likelihood values, which are then provided to a soft-input soft-output decoder. The soft-input soft-output decoder calculates output likelihood values from input likelihood values and from parity data that was previously added according to an encoding scheme.
