Abstract: A method for data storage in a non-volatile memory includes storing data in the non-volatile memory using a first storage configuration while the non-volatile memory is supplied with electrical power. After storing the data, an indication is accepted, indicating that shut-off of the electrical power is imminent. Responsively to the indication and before the shut-off, at least some of the data is re-programmed in the non-volatile memory using a second storage configuration.

Abstract: A method and apparatus for decoding a frame control header message in a wireless communication transmission are disclosed. The method comprises assuming at least some of the bits comprising the frame control header message are constant across multiple frames or are known a priori and generating metrics at least from the bits of the frame control header message that are assumed to be constant or are known a priori. The method further comprises decoding the metrics, for example, with a Viterbi decoder or using chase combining, to yield the decode frame control header message.

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.

Abstract: A method includes defining a nominal level of a physical quantity to be stored in analog memory cells for representing a given data value. The given data value is written to the cells in first and second groups of the cells, which have respective first and second programming responsiveness such that the second responsiveness is different from the first responsiveness, by applying to the cells in the first and second groups respective, different first and second patterns of programming pulses that are selected so as to cause the cells in the first and second groups to store respective levels of the physical quantity that fall respectively in first and second ranges, such that the first range is higher than and the second range is lower than the nominal level. The given data value is read from the cells at a later time.

Abstract: In general, in one aspect, the disclosure describes a method defining order and means in which physical parameters of a received OFDM signal may be detected. A fractional frequency offset is determined for the OFDM signal and is used to determine a coarse location for received signal preamble. A symbol boundary is determined based on the coarse location and the course location is used to determine preamble location. A preamble sequence and integer frequency offset is determined based on the preamble location.

Abstract: 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.
