Abstract: A method for data storage includes preparing first data having a first size for storage in a memory device that stores data having a nominal size larger than the first size, by programming a group of memory cells to multiple predefined levels using a one-pass program-and-verify scheme. The first data is combined with dummy data to produce first combined data having the nominal size, and is sent to the memory device for storage in the group. The dummy data is chosen to limit the levels to which the memory cells in the group are programmed to a partial subset of the predefined levels. In response to identifying second data to be stored in the group, the second data is combined with the first data to obtain second combined data having the nominal size, and is sent to the memory device for storage, in place, in the group.

Abstract: A method includes storing data in memory cells by programming the memory cells with respective values. The memory cells are read in multiple readout operations that each compares the programmed values to at least first and second read thresholds, while keeping the first read threshold fixed throughout the readout operations and perturbing only the second read threshold between the readout operations. A preferred value for the second read threshold is estimated based on the multiple readout operations.

Abstract: A method includes, in a memory block, which includes at least a string of memory cells that is selectable using at least a select transistor, sensing a current flowing through the string. A failure in the memory block, which causes the string to conduct even when unselected using the select transistor, is detected based on the sensed current. A corrective action is initiated in response to the identified failure.

Abstract: A method for data storage includes reading storage values, which represent stored data, from a group of memory cells using read thresholds, and deriving respective soft reliability metrics for the storage values. The storage values are classified into two or more subgroups based on a predefined classification criterion. Independently within each subgroup, a subgroup-specific distribution of the storage values in the subgroup is estimated, and the soft reliability metrics of the storage values in the subgroup are corrected based on the subgroup-specific distribution. The stored data is decoded using the corrected soft reliability metrics.

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 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.
