Abstract
A wordline activation delay monitor circuit is disclosed wherein at least one sample wordline and a sample wordline redundancy are located within the same data-storing array region of a memory, and a sample wordline selector is coupled to activate the sample wordline or sample wordline redundancy based on the state of a nonvolatile input. The wordline selector circuit may include one or both of a row decoder circuit or a wordline driver circuit which have substantially the same structure and location as row decoder circuits and wordline driver circuits used to activate wordlines within the data-storing array region.
