Abstract (en)

[origin: WO0019577A1] In order to make power consumption efficient and prolong a battery life even if constituted by a plurality of circuit blocks each being of different minimum operating voltage, a power unit according to the present invention includes a plurality of power source lines forming power lines (6a, 6b, 6c) that connect each of a memory (2), a CPU (3), and a peripheral circuit (4) to a battery in parallel, and diodes (7, 8, 9) which are electrical resistance elements that increase the electrical resistance of, among a plurality of power source lines, the power source input lines (6b, 6c) of the circuit blocks whose minimum operating voltage is low.
