FLASH MEMORY DEVICE AND HIGH VOLTAGE GENERATOR FOR THE SAME

摘要

A flash memory device and a high voltage generator for the same are provided to generate a required high voltage stably, by preventing overshoot due to high transient voltage generated from the high voltage generator efficiently. A charge pump(10) generates a high voltage in response to a pumping clock signal. A voltage divider circuit(20) enables a plurality of voltage dividing paths selectively by receiving the high voltage as a switching voltage, and outputs voltage dividing result generated by passing the high voltage through the enabled voltage dividing path. A comparison circuit(50) generates a comparison signal by comparing the voltage dividing result with a reference voltage. A clock control circuit(60) generates the pumping clock signal in response to the comparison signal.
