    摘要: Methods and apparatus are provided for soft data generation for memory devices. At least one soft data value is generated for a memory device, by obtaining at least one hard read value; and generating the soft data value associated with the at least one hard read value based on statistics for reading the hard read value. The hard read value may be one or more of data bits, voltage levels, current levels and resistance levels. The generated soft data value may be one or more of (i) a soft read value that is used to generate one or more log likelihood ratios, and (ii) one or more log likelihood ratios. The statistics comprise one or more of bit-based statistics and cell-based statistics. The statistics may also optionally comprise pattern-dependent disturbance of at least one aggressor cell on the target cell, as well as location-specific statistics. At least one soft data value can be generated for a memory device, by obtaining a soft read value; and generating the soft data value associated with the soft read value based on statistics for reading the soft read value, wherein the statistics comprise one or more of location-specific statistics and pattern-dependent statistics.

    摘要: Methods and apparatus are provided for read-side intercell interference mitigation in flash memories, A flash memory device is read by obtaining a read value for at least one target cell; obtaining a value representing a voltage stored in at least one aggressor cell that was programmed after the target cell; determining intercell interference for the target cell from the at least one aggressor cell; and obtaining a new read value that compensates for the intercell interference by removing the determined intercell interference from the read value for the at least one target cell. The new read value can optionally be provided to a decoder. In an iterative implementation, one or more intercell interference mitigation parameters can be adjusted if a decoding error occurs.

    摘要: Register exchange network for radix-4 SOVA (Soft-Output Viterbi Algorithm). Two trellis stages are processed simultaneously and in parallel with one another (e.g., during a single clock cycle) thereby significantly increasing data throughput. Any one or more modules within an REX (Register Exchange) module are implemented using a radix-4 architecture to increase data throughput. Any one or more of a SMU (Survivor Memory Unit), a PED (Path Equivalency Detector), and a RMU (Reliability Measure Unit) are implemented in accordance with the principles of radix-4 decoding processing.
