Abstract: A method for data storage includes defining, in a memory that includes multiple analog memory cells, an erased state, a set of non-erased programming states and a partial subset of the non-erased programming states. Data is initially stored in a first group of the analog memory cells by programming each of at least some of the memory cells in the first group from the erased state to a respective non-erased programming state selected from the set of non-erased programming states. After initially storing the data, a second group of the analog memory cells, which potentially cause interference to the first group, is programmed. After programming the second group, the first group is selectively re-programmed with the data by repeating programming of only the memory cells in the first group whose respective programming states belong to the partial subset.

Abstract: A method includes storing data in a group of analog memory cells by writing first storage values to the cells. After storing the data, second storage values are read from the cells using one or more first read thresholds. Third storage values that potentially cause cross-coupling interference in the second storage values are identified, and the third storage values are processed, to identify a subset of the second storage values as severely-interfered values. Fourth storage values are selectively re-read from the cells holding the severely-interfered values using one or more second read thresholds, different from the first read thresholds. The cross-coupling interference in the severely-interfered storage values is canceled using the re-read fourth storage values. The second storage values, including the severely-interfered values in which the cross-coupling interference has been canceled, are processed so as to reconstruct the data stored in the cell group.

Abstract: 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.

Abstract: A method for data storage includes defining a first programming scheme that programs a group of analog memory cells while reducing interference caused by at least one memory cell that neighbors the group, and a second programming scheme that programs the group of the analog memory cells and does not reduce all of the interference reduced by the first programming scheme. One of the first and second programming schemes is selected based on a criterion defined with respect to the analog memory cells. Data is stored in the group of the analog memory cells using the selected programming scheme.

Abstract: A method for detecting a preamble location in a multiple preamble OFDM (Orthogonal Frequency Division Multiplexing) system is disclosed. An OFDM signal is generated with a plurality of frames, and each of the frames includes symbols and a predetermined preamble symbol. A maximum FDDC (Frequency Domain Differential Correlator) value is computed for each of the symbols in some of the frames. The preamble location in a frame is determined by summing the maximum FDDC value for each symbol at a same frame location in consecutive frames of the OFDM signal.

Abstract: A method for data storage in analog memory cells includes defining multiple programming states for storing data in the analog memory cells. The programming states represent respective combinations of more than one bit and correspond to respective, different levels of a physical quantity stored in the memory cells. The data is stored in the memory cells by applying to the memory cells programming pulses that cause the levels of the physical quantity stored in the memory cells to transition between the programming states, such that a given transition is caused by only a single programming pulse.
