1. An apparatus comprising:
a die of a memory device;
a memory cell portion located over a first portion of the die;
a conductive pad portion located over a second portion of the die and outside the memory cell portion, the conductive pad portion including conductive pads, each of the conductive pads being part of a respective electrical path coupled to a conductive contact; and
a sensor circuit located directly over the second portion of the die and under the conductive pad portion, the sensor circuit including:
a first ring oscillator;
a second ring oscillator;
a selector coupled to outputs of the first and second oscillators; and
an output unit coupled to an output of the selector.
