Abstract
A supply voltage converter circuit for use in reduced geometry high-density semiconductor memory devices, capable of reducing current consumption to as small a value as possible and achieving high-speed operation. The circuit includes a reference voltage generator, for generating a constant reference voltage, and a peripheral power-supply circuit, and array power-supply circuit for providing the internal supply voltage to the peripheral and array circuits, respectively. Each of the peripheral and array power circuits includes a divider, generating a voltage proportional to said internal supply voltage; a main power-supplying part including a main differential amplifier which compares the proportional voltage with said reference voltage and is activated by a given pulse, and a main power component providing the internal source supply voltage in response to output signal of the main differential amplifier; and a sub power supply part including a sub differential amplifier comparing the proportional voltage with the reference voltage, the differential amplifier being at a constant activation state, and a sub power component providing the internal source supply voltage in response to output signal of the sub differential amplifier.
