Abstract
The embodiments of the invention provide an apparatus, method, etc. for an efficient circuit and method to measure resistance. A sense line driver for an integrated circuit memory is provided, including a sense node that receives an experiment signal from an experiment structure. An output device is connected to the sense node, wherein the output device amplifies the experiment signal. Further, a voltage divider is connected to the sense node, wherein the voltage divider includes a first device and a second device. A sensing range is controlled by an operating width/resistance range and/or an adjust signal of the second device. The adjust signal changes a gate to source voltage of the second device and holds a constant voltage over multiple sensing instances. The sensing range is different for each of the sensing instances due to a change in the operating width of the second device.
