Voltage generation circuit for use in semiconductor memory device, has voltage generator to pump boost node in response to pumping control signals from control signal generator to generate two high voltages

摘要

The circuit has a high voltage level detector (12) to detect a level of a high voltage to generate a high voltage level detection signal. A control signal generator generates three pumping control signals in response to the high voltage level detection signal. A voltage generator pumps a boost node in response to pumping control signals from the control signal generator to generate two high voltages.
