A self-refresh control circuit includes: a code generator configured to generate a code by counting periods of a periodic wave based on a self-refresh signal and reset when a code value of the generated code reaches a first value; a bank active signal generator configured to generate a plurality of bank active signals activated in response to different code values of the generated code, respectively, by decoding the generated code; and an address generator configured to change a row address after the plurality of the bank active signals are each activated after the reset of the code generator. |
