    Abstract: A method for data storage includes, in a memory that includes multiple memory blocks, specifying at a first time a first over-provisioning overhead, and storing data in the memory while retaining in the memory blocks memory areas, which do not hold valid data and whose aggregated size is at least commensurate with the specified first over-provisioning overhead. Portions of the data from one or more previously-programmed memory blocks containing one or more of the retained memory areas are compacted. At a second time subsequent to the first time, a second over-provisioning overhead, different from the first over-provisioning overhead, is specified, and data storage and data portion compaction is continued while complying with the second over-provisioning overhead.

    Abstract: A method for data storage includes storing first data bits in a set of multi-bit analog memory cells at a first time by programming the memory cells to assume respective first programming levels. Second data bits are stored in the set of memory cells at a second time that is later than the first time by programming the memory cells to assume respective second programming levels that depend on the first programming levels and on the second data bits. A storage strategy is selected responsively to a difference between the first and second times. The storage strategy is applied to at least one group of the data bits, selected from among the first data bits and the second data bits.

    Abstract: A method for operating a memory (28) includes storing data in a group of analog memory cells (32) of the memory as respective first voltage levels. After storing the data, second voltage levels are read from the respective analog memory cells. The second voltage levels are affected by cross-coupling interference causing the second voltage levels to differ from the respective first voltage levels. Cross-coupling coefficients, which quantify the cross-coupling interference among the analog memory cells, are estimated by processing the second voltage levels. The data stored in the group of analog memory cells is reconstructed from the read second voltage levels using the estimated cross-coupling coefficients.

    Abstract: A method for data storage includes, in a host system that operates alternately in a normal state and a hibernation state, reserving a hibernation storage space in a non-volatile storage device for storage of hibernation-related information in preparation for entering the hibernation state. While the host system is operating in the normal state, a storage task other than storage of the hibernation-related information is performed using at least a portion of the reserved hibernation storage space.

    Abstract: A method for data storage includes storing data, which is encoded with an Error Correction Code (ECC), in a group of analog memory cells by writing respective first storage values to the memory cells in the group. After storing the data, respective second storage values are read from the memory cells in the group, and the read second storage values are processed so as to decode the ECC. Responsively to a failure in decoding the ECC, one or more of the second storage values that potentially caused the failure are identified as suspect storage values. Respective third storage values are re-read from a subset of the memory cells that includes the memory cells holding the suspect storage values. The ECC is re-decoded using the third storage values so as to reconstruct the stored data.

    Abstract translation: 一种用于数据存储的方法包括通过将相应的第一存储值写入组中的存储器单元来将经错误校正码（ECC）编码的数据存储在一组模拟存储器单元中。 在存储数据之后，从组中的存储器单元读取相应的第二存储值，并且处理读取的第二存储值以便对ECC进行解码。 响应于对ECC的解码失败，可​​能导致故障的一个或多个第二存储值被识别为可疑存储值。 从包含存储可疑存储值的存储单元的存储器单元的子集重新读取相应的第三存储值。 使用第三存储值对ECC进行重新解码，以重建存储的数据。
