Abstract
A semiconductor system includes a plurality of memory systems (SARM, ROM, etc.) and circuit systems. The semiconductor system further includes an analog power supply circuit which is common to the memory systems. The analog power supply circuit supplies a source potential to word line drivers of the memory systems. The source potential is set to a potential different from a ground potential and a supply voltage of the semiconductor system.
