Abstract:
The present invention relates to a semiconductor device and a method for testing the same capable of reducing the number of probing pads used during wafer test. The semiconductor device includes a select circuit connected between a plurality of internal circuits to be tested and a single probing pad, for transmitting test signals inputted from the probing pads to any one of the plurality of the internal circuits according to a test mode signal generated in a wafer test mode. It is possible to reduce the number of the probing pads in the integrated circuit used for connection to a probe for contact of a probe card during wafer test. It is therefore possible to reduce test time.
