Multi-voltage generator generating program voltage, read voltage and high voltage in response to operating mode of flash memory device

摘要

Provided is a multi-voltage generator for a flash memory device including a high voltage pumping unit configured to generate a high voltage in response to an enable signal, voltage regulators, each regulator coupled to the high voltage and a control voltage and configured to generate a pumping signal, and a selector configured to select one of the pumping signals as the enable signal.
