<p>The present invention relates to a refresh control circuit of a semiconductor apparatus which can reduce the area of a circuit. The refresh control circuit comprises: a variable delay unit for delaying a signal activated in the fastest time, among a plurality of low address strobe signals activated at a fixed time interval, to generate a preliminary pulse signal; and a piled delay unit for delaying the preliminary pulse signal by a different time period and generating a plurality of refresh section pulse signals which are sequentially activated.</p> |
