Abstract
In the case where a defective normal word line in a memory cell array has been replaced with a spare word line, a word line precharge signal output from a word line precharge signal generation circuit is activated to L level during a precharge period. As a result, a normal word line activation circuit holds the defective normal word line at a precharge potential level. Accordingly, the semiconductor integrated circuit device stably conducts sensing operation even when the defective normal word line replaced with the spare word line is short-circuited to a bit line.
