Abstract: A method for data storage includes receiving in a memory device data for storage in a group of memory cells. The data is stored in the group by performing a Program and Verify (P&V) process, which applies to the memory cells in the group a sequence of programming pulses and compares respective analog values of the memory cells in the group to respective verification thresholds. Immediately following successful completion of the P&V process, a mismatch between the stored data and the received data is detected in the memory device. An error in storage of the data is reported responsively to the mismatch.

Abstract: A method includes, in a plurality of memory cells that share a common isolation layer and store in the common isolation layer quantities of electrical charge representative of data values, assigning a first group of the memory cells for data storage, and assigning a second group of the memory cells for protecting the electrical charge stored in the first group from retention drift. Data is stored in the memory cells of the first group. Protective quantities of the electrical charge that protect from the retention drift in the memory cells of the first group are stored in the memory cells of the second group.

Abstract: A method includes communicating over an interface between a controller and multiple memory dies, which comprise respective on-die terminations (ODTs) that are each connectable to the interface by the controller. A plurality of termination settings are evaluated, each termination setting specifies a respective subset of the ODTs to be connected to the interface, so as to identify a preferred termination setting in which the communication quality with a given memory die meets a predefined criterion. Subsequent communication with the given memory die is performed while applying the preferred termination setting.

Abstract: A method includes communicating between a memory controller and multiple memory devices over an interface that includes at least a control signal and an information signal. For each memory device, a respective individual skew parameter, which is indicative of a timing misalignment between the control signal and the information signal when communicating with that memory device, is produced. The respective individual skew parameter is stored coupled to each memory device. The timing misalignment is corrected at the memory device using the stored individual timing skew.

Abstract: A method in a memory that includes multiple analog memory cells arranged in a three-dimensional (3-D) configuration, includes identifying multiple groups of potentially-interfering memory cells that potentially cause interference to a group of target memory cells. Partial distortion components, which are inflicted by the respective groups of the potentially-interfering memory cells on the target memory cells, are estimated. The partial distortion components are progressively accumulated so as to produce an estimated composite distortion affecting the target memory cells, while retaining only the composite distortion and not the partial distortion components. The target memory cells are read, and the interference in the target memory cells is canceled based on the estimated composite distortion.

Abstract: A method includes storing data values in a group of memory cells that share a common isolating layer, by producing quantities of electrical charge representative of the data values at respective regions of the common isolating layer that are associated with the memory cells. A function, which relates a drift of the electrical charge in a given memory cell in the group to the data values stored in one or more other memory cells in the group, is estimated. The drift is compensated for using the estimated function.
