A sense amplifier enable signal and a tracking signal are generated in response to an indication that a sufficient voltage difference has developed across bit lines of a memory. The sense amplifier enable signal has a pulse width between a leading edge and a trailing edge. The sense amplifier enable signal is propagated along a first U-turn signal line that extends parallel to rows of the memory array and is coupled to sense amplifiers arranged in a row to generate a sense amplifier enable return signal. The tracking signal is propagated along a second U-turn signal line extending parallel to columns of the memory array to generate a tracking return signal. The sense amplifier enable return signal and the tracking return signal are logically combined to generate a reset signal. Timing of the trailing edge of the pulse width is controlled by the reset signal.
