Abstract
In a method, a first edge of a first tracking signal in a first direction of a memory array is generated. A first edge of a second tracking signal in a second direction of the memory array is generated. A first edge of a write-timing control signal is generated based on a slower edge of the first edge the first tracking signal and of the first edge of the second tracking signal. The first edge of the write-timing control signal is used to generate a second edge of the second tracking signal.
