PURPOSE: A refresh circuit is provided to reduce current consumption in a refresh operation by preventing row addresses with constant levels from being unnecessarily latched. CONSTITUTION: An enable pulse generating unit(12) generates a first enable pulse and a second enable pulse. A first address latch(13) generates a first latch address by latching a first row address in synchronization with the first enable pulse. A second address latch(14) generates a second latch address and a third latch address by latching the second row address in synchronization with the second enable pulse.
