Abstract
A semiconductor integrated circuit device including: a large scale cell array; a through wiring passing through a first region within which the large scale cell array is formed; an input buffer connected to one end of the through wiring at the boundary between the first region and a second region within which the large scale cell array is not formed, the input buffer converting the level of a signal inputted from the second region to a smaller level and transmitting the signal of the smaller level to the first region; and an output buffer circuit connected to the other end of the through wiring at the boundary, the output buffer converting the level of the signal transmitted from the first region to a larger level and transmitting the signal of large level to the second region.
