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 data storage system includes a plurality of non-volatile memory devices arranged in one or more sets, a main controller and one or more processors. The main controller is configured to accept commands from a host and to convert the commands into recipes. Each recipe includes a list of multiple memory operations to be performed sequentially in the non-volatile memory devices belonging to one of the sets. Each of the processors is associated with a respective set of the non-volatile memory devices, and is configured to receive one or more of the recipes from the main controller and to execute the memory operations specified in the received recipes in the non-volatile memory devices belonging to the respective set.

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 operating a memory (28) that includes a plurality of analog memory cells (32) includes storing data in the memory by writing first storage values to the cells. Second storage values are read from the cells, and a Cumulative Distribution Function (CDF) of the second storage values is estimated. The estimated CDF is processed so as to compute one or more thresholds. A memory access operation is performed on the cells using the one or more thresholds.
