Abstract:
A semiconductor device include a first wrapper including a first scan flip-flop, first control flip-flops and a first pad, the first scan flip-flop receiving a first value and second values and storing the second value for determining a function of the first pad; a second wrapper including a second scan flip-flop, second control flip-flops and a second pad, the second scan flip-flop receiving the first value from the first wrapper and storing the first value for determining a function of the second pad; and an input/output controller configured to provide a shift input signal having the first and second values to the first wrapper.
