    摘要: A time delay is determined to cover a timing of a memory cell in a memory macro having a tracking circuit. Based on the time delay, a capacitance corresponding to the time delay is determined. A capacitor having the determined capacitance is utilized. The capacitor is coupled to a first data line of a tracking cell of the tracking circuit. A first transition of the first data line causes a first transition of a second data line of the memory cell.
