Abstract
A device for monitoring process variations across memory bitcells includes a bitcell inverter that provides an output voltage to be used for identifying skewed corners of the memory bitcells. A first comparator compares the output voltage with a first reference voltage, and a second comparator compares the output voltage with a second reference voltage. The first and the second comparators generate a corner code based on comparison results.
