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, in a memory controller that controls a memory, evaluating an available memory space remaining in the memory to write data. A redundant storage configuration is selected in the memory controller depending on the available memory space. Redundancy information is calculated over the data using the selected redundant storage configuration. The data and the redundancy information are written to the available memory space in the memory.

Abstract: A method includes, in a non-volatile memory that includes multiple memory blocks, defining a redundancy zone that includes at least an old parity block, a new parity block and multiple active blocks of which one block is defined as an open block. Data is stored in the redundancy zone and the stored data is protected, such that new input data is stored in the open block, redundancy information for the active blocks including the open block is stored in the new parity block, and the redundancy information for the active blocks excluding the open block is stored in the old parity block. Upon filling the open block and the new parity block, an alternative block is assigned to serve as the open block and the new parity block is assigned to serve as the old parity block.
