PURPOSE: To prevent a rising signal and a trailing signal of bi-phase clock signals fed to any of integrated circuit layers A-C of the laminated integrated circuit from being overlapped with each other. CONSTITUTION: A couple of clock shaping means 3, 4, and buffer drive means 5, 8 receiving an output of the clock shape means respectively are formed into one layer B of the laminated integrated circuit. Then buffer means 9-14 delivering each output of the buffer drive means 5, 8 to a load and the means 6, 7, 21-24 feeding back an output of each buffer drive means to other clock shape means are formed to each layer of the laminated integrated circuit. No H output is obtained from a NOR circuit being the clock shape means (that is, the other clock does not rise) before outputs fed back to the NOR means being the clock shape means are all not at a low level (that is, one clock does not trail at any layer). |
