A memory device comprises a memory cell and a sense amplifier which has a sensing interval. An output circuit is coupled to the sense amplifier and responsive to a clock signal to accept the signal from the sense amplifier. A first source of timing signals generates a first timing signal in response to an enable signal which is asynchronous relative to the clock signal. A second source of timing signals generates a second timing signal based on the clock signal. A switch selects one of the first and second timing signals at the timing signals for use to define pre-charge and sensing intervals for the sense amplifier. The first source of timing signals is selected during an interval of time corresponding to a clock latency, so that the timing signals define a sensing interval where transitions in the clock signal are outside of the sensing interval.
