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 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 defining at least first and second read commands for reading storage values from analog memory cells. The first read command reads the storage values at a first accuracy, and the second read command reads the storage values at a second accuracy, which is finer than the first accuracy. A condition is evaluated with respect to a read operation that is to be performed over a given group of the memory cells. One of the first and second read commands is selected responsively to the evaluated condition. The storage values are read from the given group of the memory cells using the selected read command.

摘要： In some embodiments, a method includes accepting a code word of a composite Error Correction Code (ECC), which was produced by encoding data with multiple component ECCs, and which was received with one or more reception parameters. One or more of the component ECCs are decoded, but without fully decoding the code word. The one or more reception parameters are estimated based on the decoded component ECCs. In other embodiments, a method includes accepting a code word of an ECC, which encodes data and which was received with one or more reception parameters. An Error Locator Polynomial (ELP), having one or more roots that indicate respective locations of one or more errors in the code word, is derived from the accepted code word. The one or more reception parameters are estimated based on the ELP.

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 method for data storage in a memory that includes multiple analog memory cells fabricated using respective physical media, includes identifying a group of the memory cells whose physical media have deteriorated over time below a given storage quality level. A rejuvenation process, which causes the physical media of the memory cells in the group to meet the given storage quality level, is applied to the identified group. Data is stored in the rejuvenated group of the memory cells.
