    Abstract: A semiconductor device includes a delay time adjustment circuit and an address input circuit. The delay time adjustment circuit adjusts a point in time when charges are supplied to internal nodes according to a voltage level of a back-bias voltage in response to a test mode signal. The delay time adjustment circuit also delays an active signal by a first delay time varying according to amounts of charge of the internal nodes to generate a bank selection signal. The address input circuit is driven by the back-bias voltage. The address input circuit receives an address in response to the bank selection signal to generate an internal address. The address input circuit delays the address by a second delay time varying according to a voltage level of the back-bias voltage.
