Abstract
A memory array comprising a number of memory cells, a set path, a signal path, and at least one word line for transmitting a word line select signal to a row of the memory cells. The word line extends from a first driver end to a second end. The memory array further includes a dummy word line extending from the first driver end to a point between the first and second ends and back to the first end for transmitting a tracking signal responsive to the word line select signal. By folding the dummy word line in this manner, improved tracking of the set path with the signal path is achieved.
