    Abstract: An apparatus includes a memory and a memory controller. The memory includes a memory block that includes memory cells connected by word lines. The memory controller is configured to store data in the memory cells, and to identify a suspected short-circuit event in the memory block by recognizing a deviation of a performance characteristic of at least a given word line in the memory block relative to the performance characteristic of remaining word lines in the memory block.

    Abstract: A method in a non-volatile memory, which includes multiple memory cells that store data using a predefined set of programming levels including an erased level, includes receiving a storage operation indicating a group of the memory cells that are to be retained without programming for a long time period. The memory cells in the group are set to a retention programming level that is different from the erased level. Upon preparing to program the group of memory cells with data, the group of memory cells is erased to the erased level and the data is then programmed in the group of memory cells.

    Abstract: A method includes selecting a word line for programming in an array of analog memory cells that are arranged in rows associated with respective word lines and columns associated with respective bit lines. Word-line voltages, which program the memory cells in the selected word line, are applied to the respective word lines. Bit-line voltages, which cause one or more additional memory cells outside the selected word line to be programmed as a result of programming the selected word line, are applied to the respective bit lines. Using the applied word-line and bit-line voltages, data is stored in the memory cells in the selected word line and the additional memory cells are simultaneously programmed.

    Abstract: A method includes, in an array of analog memory cells that are arranged in rows associated with respective word lines, reading a first group of the memory cells in a selected word line, including one or more memory cells that store a status of at least one word line in the array other than the selected word line. A readout configuration for a second group of the memory cells is set responsively to the read status. The second group of the memory cells is read using the readout configuration.
