Abstract:
Apparatuses and methods of for refresh control of a semiconductor device are described. An example apparatus includes a command control circuit that provides a plurality of pulses on a first control signal in series responsive to a plurality of refresh commands issued in series; a signal generation circuit that produces a plurality of pulses on a second control signal in sequence; and a refresh control circuit that receives two or more of the plurality of pulses on the first control signal during a period of time between one pulse and a succeeding pulse of the plurality of pulses on the second control signal, disables refresh operations responsive to at least one of the two or more of the plurality of first control signal and executes a refresh operation responsive to remaining one or more pulses of the two or more of the plurality of pulses on the first control signal.
