Abstract
A semiconductor structure and a method for operating the same. The semiconductor structure includes a first semiconductor chip and a second semiconductor chip. The first semiconductor chip is on top of and bonded to the second semiconductor chip. The first and second semiconductor chips include a first and a second electric nodes. The second semiconductor chip further includes a first comparing circuit. The semiconductor structure further includes a first coupling via electrically connecting the first electric node of the first semiconductor chip to the first comparing circuit of the second semiconductor chip. The first comparing circuit is capable of (i) receiving an input signal from the second electric node directly, (ii) receiving an input signal from the first electric node indirectly through the first coupling via, and (iii) asserting a first mismatch signal in response to the input signals from the first and second electric nodes being different.
