Abstract
A NROM memory device includes an array of memory cells and first and second bit lines. The first and second bit lines are coupled to opposite sides of the memory cells. During an erase operation, one of the sides of the memory cells receives a positive voltage and the other side couples to a common node or a limited current source. Methods are also disclosed that can easily screen for marginal memory cells based on a threshold voltage distribution of the memory cells.
