Abstract
A semiconductor device for use in a semiconductor memory device for pumping a supplying voltage according to a data access mode and an auto-refresh mode, including: a voltage level detecting means for generating a voltage level detect signal by detecting a voltage level of the supplying voltage; an auto-refresh signal detecting means for generating an auto-refresh detect signal in response to an auto-refresh signal; and a voltage pumping means for pumping the supplying voltage in response to the voltage level detect signal at the data access mode or in response to the auto-refresh detect signal at the auto-refresh mode.
