Claim Text:
1. A semiconductor device including an integrated circuit on a chip, the semiconductor device comprising: a plurality of functional circuits connected to a common power source in parallel, the plurality of functional circuits including at least a first functional circuit and a second functional circuit, the first functional circuit including internally stored data; a first resistor provided on the chip in a power source side of the first functional circuit; a second resistor provided on the chip in a power source side of the second functional circuit: a first capacitor provided on the chip in parallel with the first functional circuit; and a second capacitor provided on the chip in parallel with the second functional circuit; wherein the first functional circuit includes a first predetermined minimum operating voltage level; wherein the second functional circuit includes a second predetermined minimum operating voltage level, the second predetermined minimum operating voltage level being higher than the first predetermined minimum voltage level; wherein the first capacitor is configured to maintain the first predetermined minimum operating voltage level at the first functional circuit for a first predetermined time or longer, during a transient of the power source; and wherein the second capacitor is configured to maintain the second predetermined minimum operating voltage level at the second functional circuit for a second predetermined amount of time or longer, during a transient of the power source.
