Abstract
An integrated non-volatile memory device may include a first matrix of memory cells organized into rows (or word lines) and columns (or bit lines), corresponding row and column decoding circuits, and read, modify and erase circuits for reading and modifying data stored in the memory cells. Furthermore, the memory device may also include a test structure including a second matrix of memory cells smaller than the first. The second memory matrix may include word line couplings each having a different contact to gate distance. That is, each coupling is aligned a different distance from its respective gate than adjacent couplings.
