Abstract

It has been difficult to carry out a test and an analysis with respect to combinational logic circuits mounted across plural chips, and therefore, there is provided a flip-flop (31b) by use of which either of a scan chain within a semiconductor chip (LSI_B), and a scan chain across plural semiconductor chips (LSI_A and LSI_B) can be made up.
