  • Patent number: 11972812
    Abstract: A memory system identifies memory cells connected to a common word line that have had their threshold voltage unintentionally drift lower than programmed by determining whether memory cells meet two criteria: (1) the memory cells have threshold voltages within an offset of a read compare voltage of a data state; and (2) adjacent memory cells (connected to word lines that are adjacent to the common word line) are in one or more low data states. For those memory cells meeting the two criteria, the memory system performs some amount of programming on the memory cells to refresh the data stored in those memory cells to be as originally intended.

  • Publication number: 20230377643
    Abstract: A controller is configured to program the memory cells to a first set of data states in a first programming pass and to a greater second set of data states in a second programming pass. The controller performs the first programming pass on the first word line. The controller then repeats the process of programming a portion of another word line and then comparing an upper tail of an erased data state of the first word line to a critical voltage until the upper tail of the erased data state of the first word line exceeds the critical voltage by a threshold. In response to the upper tail of the erased data state exceeding the critical voltage by the threshold, the controller then alternates between the first and second programming passes until the first programming pass is completed on the remaining word lines of the memory block.
