    Abstract: A method includes storing data in a non-volatile memory that includes multiple memory blocks. At least first and second regions are defined in the non-volatile memory. A definition is made of a first over-provisioning ratio between a first logical address space and a first physical memory space of the first region, and a second over-provisioning ratio, different from the first over-provisioning ratio, between a second logical address space and a second physical memory space of the second region. Portions of the data are compacted, individually within each of the first and second regions and independently of the other region, by copying the portions from one or more source memory blocks to one or more destination memory blocks using the first and second over-provisioning ratios, respectively.

    Abstract: A method for data storage includes, in a first programming phase, storing first data in a group of analog memory cells by programming the memory cells in the group to a set of initial programming levels. In a second programming phase that is subsequent to the first programming phase, second data is stored in the group by: identifying the memory cells in the group that were programmed in the first programming phase to respective levels in a predefined partial subset of the initial programming levels; and programming only the identified memory cells with the second data, so as to set at least some of the identified memory cells to one or more additional programming levels that are different from the initial programming levels.

    Abstract: A method for data storage in a data storage system, which includes a main storage device and a non-volatile memory, includes assessing quality levels of respective memory blocks of the non-volatile memory. One or more of the memory blocks whose assessed quality levels are lower than a predefined quality threshold are identified. The identified memory blocks are assigned to serve as read cache memory. Data is read from the main storage device via the read cache memory, including the assigned memory blocks.
