Abstract

A semiconductor device includes a driving unit suitable for driving a plurality of signal lines, which are directly coupled to a plurality of bump pads, to a preset voltage level in a level determination period, and adjusting the preset voltage level in a predetermined order when the level determination period is repeated, a signal input circuit suitable for receiving voltage levels that are inputted through the signal lines and determining logic values for the inputted voltage levels of the signal lines, and an operation unit suitable for receiving voltage levels of the signal lines from the signal input circuit in a parallel manner in the level determination period, latching the logic values of the voltage levels, and serially outputting the logic values through a probe pad.
