Patent ID: 8363481

Claim:
A non-volatile semiconductor memory device comprising: a substrate; a first word-line provided above the substrate surface, the first word-line having a plate shape in a first area where a memory cell is formed, and a first folded portion in a second area adjacent to the first area, the first folded portion further including a first plate-shape end portion parallel to the substrate at an end thereof; a second word-line provided above the first word-line surface, the second word-line having a plate shape in the first area and a second folded portion in the second area, the second folded portion further including a second plate-shape end portion parallel to the substrate at the end thereof; a plurality of metal wirings electrically connecting the first and second word-lines to a driver circuit; and a plurality of contacts electrically connecting the first plate-shape end portion and the second plate-shape end portion to the metal wirings, the first plate-shape end portion and the second plate-shape end portion being formed at a same height from the substrate.
