摘要:
A static memory circuit provided with an improved bit line precharge circuit (Q p1 - Q p3 ) includes a control circuit which disenables a bit line pull-up circuit (Q p4 , Q p5 ) during a first period through which one of the word lines (WL₁ - WL n ) to be selected performs a potential change to a selective level and enables the pull-up circuit during other period than the first period.
