The present invention is a method for fabricating a memory device. In one embodiment, a first impurity concentration is deposited in a channel region of a memory device. A second impurity concentration, which overlies the first impurity concentration, is then created in the channel region. Finally, a memory array is fabricated upon the channel region. The memory array overlies the first impurity concentration and the second impurity concentration.
