Abstract: A method for data storage includes storing data in a group of analog memory cells by writing respective input storage values to the memory cells in the group. After storing the data, respective output storage values are read from the analog memory cells in the group. Respective confidence levels of the output storage values are estimated, and the confidence levels are compressed. The output storage values and the compressed confidence levels are transferred from the memory cells over an interface to a memory controller.

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 data storage includes accepting data for storage in a memory that includes multiple analog memory cells and supports a set of built-in programming commands. Each of the programming commands programs a respective page, selected from a group of N pages, in a subset of the memory cells. The subset of the memory cells is programmed to store M pages of the data, M>N, by performing a sequence of the programming commands drawn only from the 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 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.
