Abstract

In a semiconductor device including a row-based control circuit applied with a current reduction circuit having a standby state and an active state, a refresh control circuit generates a refresh request signal every predetermined time interval on a self-refresh mode and time-sequentially generates an internal active signal at N times in connection with the refresh request signal once. The row-based control circuit time-sequentially refreshes information of memory cells on the based of the internal active signal at the N times. The refresh control circuit inactivates the row-based control circuit by making the current reduction circuit the standby state.
