An apparatus is provided which includes: a first power supply node; a second power supply node; a memory bit-cell coupled to the second power supply node; a circuitry coupled to the first and second power supply nodes, the circuitry to operate in a diode-connected mode; and a transistor coupled in parallel to the circuitry, wherein the transistor is controllable by a digital signal such that when the transistor is to turn on, it is to apply voltage and/or current stress to the memory bit-cell.
