A clock control system for a scan chain generates two clock signals. During a shift phase of a testing mode of the scan chain, one clock signal is an inverted version of the other clock signal. The clock control system provides the clock signal and the inverted clock signal to two different scan flip-flops of the scan chain, respectively. Each of the two scan flip-flops performs a flip-flop operation when the received clock signal transitions from a de-asserted state to an asserted state. Thus, the two flip-flop operations are mutually exclusive during the shift phase. As a result, a dynamic voltage drop across the scan chain during the shift phase is reduced.
