Abstract:
A wordline tracking circuit and corresponding method are disclosed, and include a tracking wordline having an impedance characteristic associated therewith that models a row of memory cells in a memory device, wherein the tracking wordline has a near end that receives a wordline pulse signal having a near end rising pulse edge and a near end falling pulse edge. The tracking wordline also has a far end. A tracking cell component is coupled to the far end of the tracking wordline that receives the wordline pulse signal. Lastly, the circuit includes a tracking bitline pre-charge circuit coupled to the tracking cell that is configured to pre-charge a tracking bitline associated with the tracking cell using the near end wordline pulse signal.
