摘要： A method for data storage includes defining at least first and second read commands for reading storage values from analog memory cells. The first read command reads the storage values at a first accuracy, and the second read command reads the storage values at a second accuracy, which is finer than the first accuracy. A condition is evaluated with respect to a read operation that is to be performed over a given group of the memory cells. One of the first and second read commands is selected responsively to the evaluated condition. The storage values are read from the given group of the memory cells using the selected read command.

摘要： 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.

摘要： A method for data storage includes initially storing a sequence of data pages in a memory that includes multiple memory arrays, such that successive data pages in the sequence are stored in alternation in a first number of the memory arrays. The initially-stored data pages are rearranged in the memory so as to store the successive data pages in the sequence in a second number of the memory arrays, which is less than the first number. The rearranged data pages are read from the second number of the memory arrays.

摘要： 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.

摘要： A method for operating a memory includes applying at least one pulse to a group of analog memory cells, so as to cause the memory cells in the group to assume respective storage values. After applying the pulse, the respective storage values are read from the memory cells in the group. One or more statistical properties of the read storage values are computed. A wear level of the group of the memory cells is estimated responsively to the statistical properties.
