    Abstract: A method includes storing data that is encoded with an Error Correction Code (ECC) in a group of analog memory cells. The memory cells in the group are read using multiple sets of read thresholds. The memory cells in the group are divided into two or more subsets. N partial syndromes of the ECC are computed, each partial syndrome computed over readout results that were read using a respective set of the read thresholds from a respective subset of the memory cells. For each possible N-bit combination of N bit values at corresponding bit positions in the N partial syndromes, a respective count of the bit positions in which the combination occurs is determined, so as to produce a plurality of counts. An optimal set of read thresholds is calculated based on the counts, and data recovery is performed using the optimal read thresholds.

    Abstract: A technique for determining a presence of a person in a room may include an electronic device transmitting an electromagnetic wireless signal of a first sensor. The technique may include receiving an electromagnetic return signal from the electromagnetic wireless signal. The technique may include detecting a potential target in the room based on the electromagnetic return signal. The technique may include determining that the potential target is in the room using a second sensor. Responsive to determining the potential target is in the room, the technique may include saving a training signature of the electromagnetic return signal for training a machine learning model. This technique can be repeated to obtain a set of training signatures corresponding to potential targets. The technique may include training, using the set of training signatures, the machine learning model to detect when a target is in the room using the first sensor.

    Abstract: A method, in a memory including multiple analog memory cells, includes segmenting a group of the memory cells into a common section and at least first and second dedicated sections. Each dedicated section corresponds to a read threshold that is used for reading a data page to be stored in the group. Data to be stored in the group is jointly balanced over a union of the common section and the first dedicated section, and over the union of the common section and the second dedicated section, to create a balanced page such that for each respective read threshold an equal number of memory cells will be programmed to assume programming levels that are separated by the read threshold. The balanced page is stored to the common and dedicated sections, and the read thresholds are adjusted based on detecting imbalance between data values in readout results of the balanced page.

    Abstract: A method includes dividing a group of analog memory cells into multiple subsets. The memory cells in the group are sensed simultaneously by performing a single sense operation, while applying to the subsets of the memory cells respective different sets of read thresholds, so as to produce respective readout results. An optimal set of the read thresholds is estimated by processing the multiple readout results obtained from the respective subsets using the different sets of the read thresholds.

    Abstract: A controller includes an interface and a processor. The interface is configured to communicate with a nonvolatile memory including multiple memory cells organized in multiple memory blocks that each includes multiple Word Lines (WLs). The processor is configured to store first data in one or more WLs of a memory block, the first data occupies less than a maximal number of WLs available in the memory block, to calculate redundancy data over the first data and store the redundancy data in a dedicated memory, to program second data to a selected WL of the memory block that was not programmed with the first data, to check a programming status resulting from the programming of the selected WL, and in response to identifying that programming the second data to the selected WL has corrupted at least part of the first data, to recover the first data using the redundancy data.

    Abstract: A method includes, in a memory that includes two or more memory units, storing a code word of an Error Correction Code (ECC) that is representable by a plurality of check equations, such that a first part of the code word is stored in a first memory unit and a second part of the code word is stored in a second memory unit. A subset of the check equations, which operate only on code word bits belonging to the first part stored in the first memory unit, is identified. The first part of the code word is retrieved from the first memory unit, and a count of the check equations in the identified subset that are not satisfied by the retrieved first part of the code word is evaluated. One or more readout parameters, for readout from the first memory unit, are set depending on the evaluated count.
