| Zusammenfassung: | A flash memory design with a compact threshold voltage distribution and a method for compacting the threshold voltage for a flash memory design in which the threshold voltage is compacted by erasing a plurality of memory cells to set the threshold voltage for the memory cells substantially towards a median erased threshold voltage; verifying at least one fast-erase memory cell; selectively soft-programming the memory cells; and erasing subsequent to selectively soft-programming. |
