摘要：
Tracking circuitry is described for use in a memory device. The tracking circuitry be used to monitor word line voltages in a dynamic random access memory (DRAM) and includes a comparator circuit which compares a simulated word line signal to a digit line equilibrate bias voltage. The equilibrate bias voltage is generated using either memory column circuitry or a linear resistor voltage divider.
