  • Patent number: 11527273
    Abstract: A column control circuit may include a column control signal generation circuit and a column access block signal generation circuit. The column control signal generation circuit is configured to activate an input/output strobe signal when a column access block signal is deactivated. The column control signal generation circuit is configured to deactivate the input/output strobe signal when the column access block signal is activated. The column access block signal generation circuit is configured to activate the column access block signal when gap-less read commands may be inputted. The column access block signal generation circuit may deactivate the column access block signal during a period corresponding to an N-th read command among the gap-less read commands. N is an integer that is no less than 2.
