Abstract
A memory device comprises a memory array, a plurality of access word lines, and a first tracking word line. The memory array may include a plurality of bit cells arranged over a plurality of rows and a plurality of columns. The plurality of access word lines may extend along a lateral direction. The plurality of rows may operatively correspond to the plurality of access word lines, respectively. The first tracking word line may also extend along the lateral direction and have a first portion extending from an edge of the memory array to a middle of the memory array and a second portion extending from the middle of the memory array to the edge of the memory array. The first combination can be different from the second combination.
