    Abstract: A method includes, in a host that stores data in a storage device, detecting an event that is indicative, statistically and not deterministically, of an imminent power shutdown in the host. A notification is sent to the storage device responsively to the detected event, so as to cause the storage device to initiate preparatory action for the imminent power shutdown.

    Abstract: A method, in a memory including multiple analog memory cells, includes segmenting a group of the memory cells into a common section and at least first and second dedicated sections. Each dedicated section corresponds to a read threshold that is used for reading a data page to be stored in the group. Data to be stored in the group is jointly balanced over a union of the common section and the first dedicated section, and over the union of the common section and the second dedicated section, to create a balanced page such that for each respective read threshold an equal number of memory cells will be programmed to assume programming levels that are separated by the read threshold. The balanced page is stored to the common and dedicated sections, and the read thresholds are adjusted based on detecting imbalance between data values in readout results of the balanced page.

    Abstract: A method for data storage includes reading from a memory device data that is stored in a group of memory cells as respective analog values, and classifying readout errors in the read data into at least first and second different types, depending on zones in which the analog values fall. A memory quality that emphasizes the readout errors of the second type is assigned to the group of the memory cells, based on evaluated numbers of the readout errors of the first and second types.

    Abstract: A memory system includes an interface and storage circuitry. The interface is configured to communicate with memory cells that store data. The storage circuitry is configured to program a data unit to a first group of the memory cells, to read the data unit from the first group using at least a read threshold to produce a first readout, and in response to detecting that reading the data unit has failed because the read threshold has fallen outside a supported range of read thresholds, due to a temperature difference between a time of programming the first group and a time of reading the first group, to program a second group of the memory cells. The circuitry is further configured to re-read the data unit from the first group using the at least read threshold to produce a second readout, and to recover the data unit from the second readout.

    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 data storage method includes identifying, in a set of data items associated with respective logical addresses for storage in a memory, a first subset of the logical addresses associated with the data items containing application data, and a second subset of the logical addresses associated with the data items containing parity information that has been calculated over the application data. The data items associated with the first identified subset are stored in one or more first physical memory areas of the memory, and the data items associated with the second identified subset are stored in one or more second physical memory areas of the memory, different from the first physical memory areas. A memory management task is performed independently in the first physical memory areas and in the second physical memory areas.
