ABSTRACT:
Disclosed herein are an internal voltage generation control circuit and an internal voltage generation circuit using the same. The internal voltage generation control circuit comprises a row active controller for enabling a first internal voltage generation control signal when a row active signal is enabled upon input of an active command and then disabling the first internal voltage generation control signal after the lapse of a first predetermined delay time if an RAS activation guarantee signal is enabled at a RAS active time after the first internal voltage generation control signal is enabled, an input/output controller for enabling a second internal voltage generation control signal when the row active signal and at least one of a data input signal and a data output signal are enabled and then disabling the second internal voltage generation control signal after the lapse of a second predetermined delay time if a row precharge signal is enabled or if the data input signal and data output signal are disabled, and a row precharge controller for enabling a third internal voltage generation control signal for a third predetermined delay time if the row precharge signal is enabled.
