Abstract
A tracking circuit in a memory macro includes a data line, a tracking cell electrically coupled with the data line, a logical gate, a feedback transistor, and a plurality of pulling devices. The logical gate has an input terminal and an output terminal. The input terminal of the logical gate is electrically coupled with the data line. The feedback transistor has a first terminal, a second terminal, and a gate terminal. The first terminal of the feedback transistor is electrically coupled with the data line, and the gate terminal of the feedback transistor is electrically coupled with the output terminal of the logical gate. The plurality of pulling devices is configured to pull the second terminal of the feedback transistor toward a first voltage.
