Abstract
Methods and apparatus are disclosed, such as those involving a flash memory device that includes a memory block. The memory block includes a plurality of data lines extending substantially parallel to one another, and a plurality of memory cells. One such method includes erasing the memory cells; and performing erase verification on the memory cells. The erase verification includes determining one memory cell by one memory cell whether the individual memory cells coupled to one of the data lines have been erased. The method can also include performing a re-erase operation that selectively re-erases unerased memory cells based at least partly on the result of the erase verification.
