  • Patent number: 11935620
    Abstract: A memory device for memory cell programming and erasing with refreshing operation is disclosed. The memory device includes multiple location-related memory cells and a refresh module. The location-related memory cells are coupled to a bit line on which a selecting voltage is applied. The refresh module rewrites a stored data of a first cell of the location-related memory cells to the first cell of the location-related memory cells in response to an operation count being smaller than a number N. N is related to the number of the location-related memory cells.
