Abstract
A semiconductor device includes a peripheral circuit and a core circuit. The peripheral circuit enters a smart refresh mode in which a smart refresh operation is performed based on a command. The peripheral circuit generates a latch address signal from a target address signal to output the latch address signal through a global input/output (I/O) line in the smart refresh mode. The core circuit performs an adding operation and a subtracting operation of the latch address signal to generate first and second internal address signals. The core circuit performs the smart refresh operation for first and second banks based on the first and second internal address signals.
