| 摘要 |
The present invention provides a method and apparatus for erasing memory blocks. The apparatus includes a first plurality of memory cells formed in a substrate and a second plurality of memory cells formed in the substrate. The apparatus further includes a bias circuit adapted to provide an erasing voltage differential to the first plurality of memory cells and a compensating voltage differential to the second plurality of memory cells, wherein the erasing voltage differential is larger than the compensating voltage differential.
