Abstract
A semiconductor device includes a decoder, a first register unit, and a second register unit. The decoder generates first and second register control signals in response to an external test code signal. The first register unit is coupled to the decoder. The first register unit receives the first register control signal from the decoder. The first register unit outputs in series a plurality of test signals in response to the first register control signal. The second register unit is coupled to the first register unit. The second register unit receives the first and second register control signals from the decoder. The second register unit receives in series the plurality of test signals from the first register unit in response to the first register control signal. The second register unit outputs in parallel the plurality of test signals in response to the second register control signal.
