Abstract
A memory macro includes a plurality of segments corresponding to a plurality of tracking circuits. Each segment of the plurality of segments thereby corresponds to one tracking circuit of the plurality of tracking circuits. In response to a read operation of a memory cell of a segment, a tracking circuit corresponding to the segment is configured to generate an edge of a tracking signal based on which a first edge of a cell signal associated with the memory cell is generated.
