    摘要: A method for data storage includes storing data in a group of analog memory cells by writing respective storage values into the memory cells in the group. One or more of the memory cells in the group are read using a first readout operation that senses the memory cells with a first sense time. At least one of the memory cells in the group is read using a second readout operation that senses the memory cells with a second sense time, longer than the first sense time. The data stored in the group of memory cells is reconstructed based on readout results of the first and second readout operations.

    摘要: 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.
