    摘要: Methods and apparatus are provided for write-side intercell interference mitigation in flash memories. A flash memory device is written by obtaining program data to be written to at least one target cell in the flash memory; obtaining one or more bits of program data for at least one aggressor cell to be programmed later than the target cell: and precompensating for intercell interference for the target cell by generating precompensated program values. The aggressor cells comprise one or more cells adjacent to the target cell, such as adjacent cells in a same wordline as the target cell and/or cells in an upper or lower adjacent wordline to the target cell. The precompensated program values for the target cell are optionally provided to the flash memory.

    摘要: Methods and apparatus are provided for soft data generation for memory devices using reference cells. At least one soft data value is generated in a memory device by writing a known data to one or more reference cells; reading one or more of the reference cells; obtaining a read statistic based on the read one or more reference cells; and obtaining the at least one soft data value based on the obtained read statistic. The read statistics can optionally be obtained for one or more desired locations of a memory array; or for a given pattern, PATT, in one or more aggressor cells. The read statistic can optionally comprise asymmetric statistics obtained for a plurality of possible values.

    摘要: Methods and apparatus are provided for soft data generation for memory devices based on a performance factor adjustment. At least one soft data value is generated for a memory device, by obtaining at least one read value; and generating the soft data value based on the obtained at least one read value and an adjustment based on one or more performance factors of the memory device. The read values may comprise, for example, data bits, voltage levels, current levels or resistance levels. The read values may be soft data or hard data. The possible performance factors include endurance, number of read cycles, retention time, temperature, process corner, inter-cell interference impact, location within the memory array and a pattern of aggressor cells. One or more pattern-dependent performance factors and/pr location- specific performance factors may also be considered. The generated soft data value may be a soft read value that is used to generate one or more log likelihood ratios, or may be the log likelihood ratios themselves.

    摘要: Methods and apparatus are provided for processing a data value in a read channel of a memory device. The data value provided to a general purpose processor for processing. The data value is not decoded data and may comprise one or more of a raw data value and an intermediate data value. The data value can be provided to the general purpose processor, for example, upon a detection of one or more predefined trigger conditions. A data value can be obtained from a memory device and then be redirected to a general purpose processor. The data value is not decoded data. The redirection can be conditionally performed if one or more predefined bypass conditions exist. The general purpose processor is optionally time-shared with one or more additional applications.
