Abstract
A semiconductor device includes a period signal generation circuit and an interruption signal generation circuit. The period signal generation circuit generates a period signal in response to a refresh pulse and an end pulse. The interruption signal generation circuit generates an interruption signal for controlling an operation that an address is set as a target address, if the address having the same logic level combination as the target address is inputted while the period signal is enabled.
