发明名称 Semiconductor device having a scan path
摘要 In a semiconductor device including a logic gate combination circuit and a plurality of scan registers or flip-flops, a scan path is provided to serially connect the flip-flops to each other. Scan clock signals are sequentially generated and transmitted to the scan registers. A delay time among the scan clock signals is approximately smaller than an operation time of each of the scan registers.
