    Abstract: An example method includes, performing a first erase verify on a first set of memory cells of a portion of an array of memory cells, performing a second erase verify on a second set of memory cells of the portion of the array, applying a first erase voltage pulse concurrently to each memory cell in the portion of the array if the first set fails the first erase verify and if the second set fails the second erase verify, and applying a second erase voltage pulse concurrently to each memory cell in the portion of the array if the first set passes the first erase verify and if the second set fails the second erase verify. The second erase voltage pulse is different than the first erase voltage pulse.

    Abstract: Apparatuses and methods for reprogramming memory cells are described. One or more methods for memory cell operation includes programming a number of memory cells such that each of the number of memory cells are at either a first program state or a second program state, the second program state having a first program verify voltage associated therewith; and reprogramming the number of memory cells such that at least one of the number of memory cells is reprogrammed to a third program state having a second program verify voltage associated therewith, wherein those of the number of memory cells having a threshold voltage less than the second program verify voltage represent a same data value.
