ABSTRACT:
A first plane of memory cells is formed on mesas of the array. A second plane of memory cells is formed in valleys adjacent to the mesas. The second plurality of memory cells is coupled to the first plurality of memory cells through a series connection of their source/drain regions. Wordlines couple rows of memory cells of the array. Metal shields are formed between adjacent wordlines and substantially parallel to the wordlines to shield the floating gates of adjacent cells.
