SEMICONDUCTOR DEVICE INCLUDING AN INTERNAL VOLTAGE GENERATION CIRCUIT FOR GENERATING AN INTERNAL VOLTAGE USING A REFERENCE VOLTAGE

摘要

PURPOSE: A semiconductor device is provided to change the levels of all internal voltages using a reference voltage once by changing the level of the reference voltage according to a control signal.;CONSTITUTION: A band gap unit(1010) generates a band gap voltage to keep a constant level. A reference voltage generator(1020) generates a reference voltage by dividing the band gap voltage. An internal voltage generating circuit(1030-1060) generates each internal voltage based on the reference voltage. A serial resistor divides the band gap voltage. A selection unit outputs one of voltages outputted from each connection node of a plurality of serial resistors as the reference voltage.;COPYRIGHT KIPO 2010
