Patent ID: 7227794

Claim:
An internal voltage generation control circuit comprising: a row active controller for outputting a first internal voltage generation control signal in response to a row active signal and a row address strobe (RAS) activation guarantee signal, the row active controller enabling the first internal voltage generation control signal when the 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 the 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 outputting a second internal voltage generation control signal in response to a data input signal, a data output signal, the row active signal and a row precharge signal, the input/output controller enabling the second internal voltage generation control signal when the row active signal and at least one of the data input signal and 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 the row precharge signal is enabled or if the data input signal and data output signal are disabled; and a row precharge controller for outputting a third internal voltage generation control signal in response to the row precharge signal, the row precharge controller enabling the third internal voltage generation control signal for a third predetermined delay time if the row precharge signal is enabled.
