Active control device, semiconductor device and system including the same

摘要

Disclosed herein are an active control device, a semiconductor device and system including the same. The active control device may include a refresh control unit configured for outputting a refresh signal by controlling a delay time for a refresh start time when a refresh operation is performed and a precharge signal generation unit configured for generating a bank precharge signal for precharging a bank in response to the refresh signal. The refresh control unit may include a refresh delay unit for delaying a bank-active signal for a specific time and outputting a delay signal, and the refresh delay unit may be operably coupled with a plurality of banks in common.
