ABSTRACT:
A voltage regulator comprises resistor elements that mitigate variations in a program voltage (VPROG). In particular, the resistors allow copies of the voltage regulator to be fabricated more consistently across a semiconductor substrate. As such, variations in respective program voltages applied to different bitlines of a memory arrangement are mitigated. This mitigates yield loss as more devices perform as desired, thus necessitating fewer discards.
