Abstract
Disclosed herein is a dynamic type circuit which transmits a signal between relatively long-distant circuit blocks lying within a semiconductor integrated circuit chip. A whole signal path thereof comprises a plurality of sections. A section formed by a first type of signal line, which is precharged to a high level and to which a decision as to whether it is driven to a low level according to a signal inputted from a preceding section or it is left in floating state, is made, and a section formed by a second type of signal line, which is precharged to a low level in reverse and to which a decision as to whether it is driven to a high level according to a signal inputted from a preceding section or it is left in a floating state, is made, exist in alternate shifts. The respective sections are respectively connected to preceding-stage sections through MOS transistors for driving signal lines for the sections. MOS transistors for precharge are respectively connected to the signal lines for the respective sections at plural positions where a signal line is partitioned into substantially uniform intervals.
