摘要:
A semiconductor integrated circuit device includes normal bit cells, structural dummy bit cells and timing dummy bit cells having the same structure as that of the normal bit cells, normal word lines electrically connected to the normal bit cells, a first dummy word line electrically coupled to the structural dummy bit cells, and a second dummy word line electrically coupled to the timing dummy bit cells. The second dummy word line is connected in parallel with the first dummy word line.
