Abstract
In a semiconductor integrated circuit, the number of rows of transistors in each of first driver circuits is increased or decreased using MOS transistors group in clock driver circuits regions arranged in an array, such as in portions of circuit cell regions into which a core region is divided, in order to supply clock signals to cell, such as a megacell, through a mesh of interconnected clock signal supply lines, in the core region.
