Abstract
A semiconductor device includes a plurality of channels. Each of the channels includes a plurality of banks sequentially activated at intervals of a predetermined time in response to a refresh command; a comparator, when the refresh command is input to a corresponding channel, configured to detect whether the refresh command is applied to a contiguous channel; a delay decision unit configured to output a control signal to determine a bank active delay time in response to an output signal of the comparator; and a delay circuit configured to control an active delay time of the plurality of banks in response to an output signal of the delay decision unit.
