Abstract
An apparatus for expressing circuit version identification (VID) includes multiple conductive layers, a circuit VID unit, and a first and a second pull-up or pull-down circuits. Each of the conductive layers includes a first and a second conductive line. The first pull-up or pull-down circuit is coupled to the first conductive line. An input terminal of the circuit VID unit is coupled to the second conductive line. An output terminal of the circuit VID unit outputs the circuit VID. The second pull-up or pull-down circuit is coupled to the input terminal of the circuit VID unit. When the circuit VID needs to be in a first state, the first conductive line and the second conductive line are disconnected from each other. On the other hand, when the circuit VID needs to be in a second state, the first conductive line and the second conductive line are coupled to each other.
