Abstract
A memory macro includes a first memory cell array, first tracking circuit, first pre-charge circuit coupled to a first end of the first tracking bit line and a second pre-charge circuit coupled to a second end of the first tracking bit line. The first tracking circuit includes a first set of memory cells configured as a first set of loading cells responsive to a first set of control signals, a second set of memory cells configured as a first set of pull-down cells responsive to a second set of control signals, and a first tracking bit line. The first set of pull-down cells and first set of loading cells are configured to track a memory cell of the first memory cell array. The first and second pre-charge circuit are configured to charge the first tracking bit line to a voltage level responsive to a third set of control signals.
