    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 for operating a memory includes storing data in a plurality of analog memory cells that are fabricated on a first semiconductor die by writing input storage values to a group of the analog memory cells. After storing the data, multiple output storage values are read from each of the analog memory cells in the group using respective, different threshold sets of read thresholds, thus providing multiple output sets of the output storage values corresponding respectively to the threshold sets. The multiple output sets of the output storage values are preprocessed by circuitry that is fabricated on the first semiconductor die, to produce preprocessed data. The preprocessed data is provided to a memory controller, which is fabricated on a second semiconductor die that is different from the first semiconductor die. so as to enable the memory controller to reconstruct the data responsively to the preprocessed data.

    Abstract: A method for data storage includes defining a first programming scheme that programs a group of analog memory cells while reducing interference caused by at least one memory cell that neighbors the group, and a second programming scheme that programs the group of the analog memory cells and does not reduce all of the interference reduced by the first programming scheme. One of the first and second programming schemes is selected based on a criterion defined with respect to the analog memory cells. Data is stored in the group of the analog memory cells using the selected programming scheme.

    Abstract: 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.
