摘要： A method for data storage includes storing data in analog memory cells by programming the memory cells with respective analog input values. After storing the data, respective analog output values are read from the memory cells using multiple read thresholds, which define multiple ranges of the analog output values. Respective numbers of read errors in the data, corresponding to the analog output values falling in the ranges, are assessed. The stored data is recovered based on respective numbers of the read errors assessed in the ranges.

摘要： A method for data storage includes, in a first programming phase, storing first data in a group of analog memory cells by programming the memory cells in the group to a set of initial programming levels. In a second programming phase that is subsequent to the first programming phase, second data is stored in the group by: identifying the memory cells in the group that were programmed in the first programming phase to respective levels in a predefined partial subset of the initial programming levels; and programming only the identified memory cells with the second data, so as to set at least some of the identified memory cells to one or more additional programming levels that are different from the initial programming levels.

摘要： A method for operating a memory (28) that includes a plurality of analog memory cells (32) includes storing data in the memory by writing first storage values to the cells. Second storage values are read from the cells, and a Cumulative Distribution Function (CDF) of the second storage values is estimated. The estimated CDF is processed so as to compute one or more thresholds. A memory access operation is performed on the cells using the one or more thresholds.

摘要： A method for data storage includes accepting data for storage in an array of analog memory cells, which are arranged in rows associated with respective word lines. At least a first page of the data is stored in a first row of the array, and at least a second page of the data is stored in a second row of the array, having a different word line from the first row. After storing the first and second pages, a third page of the data is stored jointly in the first and second rows.

摘要： A method for data storage includes accepting data for storage in a memory including multiple analog memory cells. For each memory cell, a respective set of nominal analog values is assigned for representing data values to be stored in the memory cell, by choosing the nominal analog values for a given memory cell in a respective range that depends on interference between the given memory cell and at least one other memory cell in the memory. The data is stored in each memory cell using the respective selected set of the nominal analog values.

摘要： A decoding apparatus includes a decoder and a control unit. The decoder includes circuitry that is configured to decode an Error Correction Code (ECC) by operating in one of a first operational mode having a first power consumption, and a second operational mode, in which at least part of the circuitry that is active during the first operational mode is deactivated and which has a second power consumption that is lower than the first power consumption. The control unit is configured to evaluate a criterion with respect to an input code word, to select one of the first and second operational modes responsively to the criterion, and to invoke the decoder to decode the input code word using the selected operational mode.

摘要： A method for data storage includes storing data in a group of analog memory cells by writing into the memory cells in the group respective storage values, which program each of the analog memory cells to a respective programming state selected from a predefined set of programming states. The programming states include at least first and second programming states, which are applied respectively to first and second subsets of the memory cells, whereby the storage values held in the memory cells in the first and second subsets are distributed in accordance with respective first and second distributions. Respective first and second medians of the first and second distributions are estimated, and a read threshold is calculated based on the first and second medians. The data is retrieved from the analog memory cells in the group by reading the storage values using the calculated read threshold.

摘要： A method for data storage includes providing a mapping of data pages to physical pages, in which each physical page holds a non-integer number of the data pages, for storage of data in at least one memory block, including a plurality of the physical pages, in a memory device. The data pages that are mapped to the memory block are partitioned into groups, such that failure of any memory unit, which consists of a predefined number of the physical pages in the memory device, will produce errors in no more than one data page in each group. The data pages is stored in the physical pages of the memory block in accordance with the mapping, while a redundant storage scheme is applied among the data pages of each group.
