Semiconductor integrated circuit

摘要

Disclosed herein is a semiconductor integrated circuit including: a cell layout region including circuit cells subject to power control the supply and interruption of power to which is controlled by a power switch, and always-on circuit cell groups which are always powered after the activation; a main line laid out in the cell layout region and applied with a source or reference voltage; and first and second branch lines which branch from the main line in the cell layout region.

主权项

1. A semiconductor integrated circuit comprising:
a power switch configured to provide electrical connection and disconnection between a first branch line and a main line, said main line extending along a first direction; a peripheral circuit cell electrically connected to said first branch line, said first branch line extending along a second direction; a branch connection circuit cell electrically connected to a second branch line, said second branch line extending along said second direction; an individual connection circuit cell electrically connected to an individual connection line, said individual connection line being electrically connected to said main line, wherein said individual connection line is shorter than said first branch line, said individual connection line being shorter than said second branch line, wherein said first branch line is in a first wiring layer and said second branch line is in a second wiring layer, said second wiring layer being between said first wiring layer and said main line.
