Claim:
1. A printed circuit board (PCB) comprising: an in-line PCB region comprising an input/output control region including a first conductive line; and a main PCB region coupled to the in-line PCB region and comprising a semiconductor chip and an input/output signal generation region including a second conductive line; wherein the in-line PCB region of the printed circuit board and the main PCB region of the printed circuit board are separated by a PCB cutting line at which the main PCB region is separable from the in-line PCB region; and wherein the input/output signal generation region is configured to detect whether or not the first and second conductive lines are electrically connected and to provide an input/output control signal to the semiconductor chip in response to determining whether or not the first and second conductive lines are electrically connected, wherein the second conductive line is connected between a first end of the first conductive line and the semiconductor chip, and wherein the main PCB region further comprises a third conductive line that is connected to a second end of the first conductive line, a source voltage is connected to the second conductive line and a ground voltage is connected to the third conductive line, and wherein the ground voltage is provided to the semiconductor chip through the first and second conductive lines before the main PCB region is separated from the printed circuit board and the source voltage is provided to the semiconductor chip after the main PCB region is separated from the printed circuit board.
