    Abstract: A method for data storage includes storing data in a group of analog memory cells by writing respective input storage values to the memory cells in the group. After storing the data, respective output storage values are read from the analog memory cells in the group. Respective confidence levels of the output storage values are estimated, and the confidence levels are compressed. The output storage values and the compressed confidence levels are transferred from the memory cells over an interface to a memory controller.

    Abstract: A method for data storage includes assigning in a memory that includes one or more storage devices a first storage area for storage of user data, and a second storage area, which is separate from the first storage area, for storage of redundancy information related to the user data. Input data is processed to produce redundancy data, and the input data is stored in the first storage area using at least one first write command. The redundancy data is stored in the second storage area using at least one second write command, separate from the first write command.

    Abstract: A method for data storage includes defining a set of scrambling sequences, each sequence including bits in respective bit positions having bit values, such that a distribution of the bit values in any give bit position satisfies a predefined statistical criterion. Each data word is scrambled using a respective scrambling sequence selected from the set. The scrambled data words are stored in the memory device.

    Abstract: A method for data storage includes predefining an order of programming a plurality of analog memory cells that are arranged in rows. The order specifies that for a given row having neighboring rows on first and second sides, the memory cells in the given row are programmed only while the memory cells in the neighboring rows on at least one of the sides are in an erased state, and that the memory cells in the given row are programmed to assume a highest programming level, which corresponds to a largest analog value among the programming levels of the cells, only after programming all the memory cells in the given row to assume the programming levels other than the highest level. Data is stored in the memory cells by programming the memory cells in accordance with the predefined order.

    Abstract: A method for data storage includes accepting data for storage in a memory that includes multiple analog memory cells and supports a set of built-in programming commands. Each of the programming commands programs a respective page, selected from a group of N pages, in a subset of the memory cells. The subset of the memory cells is programmed to store M pages of the data, M>N, by performing a sequence of the programming commands drawn only from the set.

    Abstract: A method for data readout includes storing two or more candidate sets of read thresholds for reading from a memory device that includes a plurality of analog memory cells. A group of the memory cells from which data is to be read is identified. An order is defined among the candidate sets of the read thresholds responsively to a criterion defined over the group of the memory cells. Data readout from the group of the memory cells is attempted by iterating over the candidate sets according to the order, until the data is read successfully.

    Abstract: Methods and arrangements for wireless communications are described. Embodiments include transformations, code, state machines or other logic to receive from a transmitter a signal representing a known sequence of symbols. The signal may be transmitted over a plurality of sub channels. The embodiments may also include determining channel responses at the sub channels and determining a reception of the known sequence. The determining may include treating the channel responses at the sub channels in a differential manner to cancel out channel phase responses and obtain channel amplitudes. In some embodiments, the cancelling may be performed by multiplying frequency domain values representing reception of a sub channel by the complex conjugate of frequency domain values of a neighboring sub channel. Many embodiments may also include calculating a carrier to interference and noise ratio (CINR) of the signal. In several embodiments, the signal may represent the preamble of a wireless frame.
