Abstract
A circuit includes a tracking word line, a power switch, a tracking bit line, a sense circuit. The power switch is coupled between the tracking word line and a first node. The power switch is configured to discharge a voltage level on the first node in response to a clock pulse signal transmitted through the tracking word line to the power switch. The tracking bit line is coupled between the first node and a plurality of tracking cells in a memory array. The sense circuit is coupled between the first node and a second node. The sense circuit is configured to generate a negative bit line enable signal in response to that the voltage level on the first node is below a threshold voltage value of the sense circuit.
