    • 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 row 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.
    • 公开了一种字线跟踪电路和相应的方法,并且包括具有与之相关联的阻抗特性的跟踪字线,其对存储器件中的一行存储器单元进行建模,其中跟踪字线行具有近端,其接收具有 近端上升脉冲沿和近端下降脉冲沿。 跟踪字线也有一个远端。 跟踪单元组件耦合到接收字线脉冲信号的跟踪字线的远端。 最后,电路包括耦合到跟踪单元的跟踪位线预充电电路,其被配置为使用近端字线脉冲信号对与跟踪单元相关联的跟踪位线进行预充电。
