Abstract
A semiconductor device includes a random number generation circuit configured to generate a plurality of random signals according to a sampling signal; an active counter configured to count a number of inputs of an active command during a sampling period defined by the sampling signal to generate an active count signal; a replacement control circuit configured to compare the active count signal with each of the plurality of random signals to generate a replacement control signal; and a sampling latch configured to replace a sampling address with an input address according to the replacement control signal, and output the sampling address according to the sampling signal.
