Abstract
A semiconductor memory device reduces power consumption during a refresh operation. The semiconductor memory device comprises a voltage generator, a sensing controller, an output driver and a data transmitter. The voltage generator is configured to generate an internal power voltage, which is lower during a power saving mode than during a normal mode, for a peripheral area. The sensing controller is configured to generate a control signal corresponding to a level of the internal power voltage. The output driver is configured to drive a transmitting data by using an output voltage. The data transmitter is configured to convert an inputting data into the transmitting data by using the internal power voltage or convert the inputting data into the transmitting data by using the output voltage in response to the control signal.
