The converter system comprises a reference voltage generator (40) for generating a const. voltage (VREF) and two power supply circuit (20P,20A) for providing a internal supply voltage (InVcc) to the peripheral and array circuits, respectively. Each of the power circuits (20P,20A) comprises a devider (2) generating a voltage (Vp) proportional to InVcc; a main pwer supply unit (22M) including a main differential amplifier (30P,30A) comparing Vp with VREF, and being activated by as pulse (ENP, ENA) when a high load current in requided, and a main power component (32P,32A) providing InVcc; and a subsidiary power supply unit (22S) including a differential amplifier (31P,31A) and a power component (33P,33A).
