Abstract
A circuit includes a tracking bit line, a tracking unit connected to the tracking bit line and a detection unit. The tracking unit is configured to receive a first control signal and configured to selectively charge or discharge a voltage on the tracking bit line in response to the first control signal. The detection unit is coupled to the tracking bit line and configured to generate a sense amplifier enable (SAE) signal in response to the voltage level on the tracking bit line.
