SEMICONDUCTOR DEVICE INCLUDING A CONTROL SIGNAL GENERATION CIRCUIT ALLOWING REDUCTION IN SIZE

摘要

A control signal generation circuit according to the present invention includes a plurality of control circuits supplying different internal control signals as outputs, respectively, and a common delay circuit. The common delay circuit includes a plurality of delay circuits for delaying a control signal serving as a reference. These delay circuits are connected in series and output signals of respective delay circuits can be taken out through taps provided corresponding thereto. Each of the plurality of control circuits sets a signal level of a corresponding internal control signal according to the change in a signal level of a corresponding tap.
