Abstract
An internal voltage supply circuit may Include a first internal voltage generator for receiving an external voltage and generating a first internal voltage, a second internal voltage generator for generating a second internal voltage lower than the first internal voltage, and a switching circuit responsive to a control signal, for supplying the second internal voltage to a refresh-associated circuit in a refresh mode and the first internal voltage to the refresh-associated circuit in normal mode. The control signal is enabled in the refresh mode.
