IC power source, various IC products provided with same, method for supplying power to IC, and method for driving IC

An integrated circuit (IC) substrate with a mounted secondary battery comprising:

• a printed wiring board;
• a plurality of IC chips mounted on the printed wiring board;
• a plurality of all-solid-state lithium secondary batteries mounted in an area directly on or above or directly below the IC chip or within 1 cm from the outer edge of the IC chip, wherein each of the all-solid-state lithium secondary batteries comprises a positive electrode layer, a solid electrolyte layer and a negative electrode layer, wherein the solid electrolyte layer has a thickness of 0.1 to 20 μm and longitudinal and transverse dimensions in a range of 1 to 50 mm,
• wherein at least one all-solid-state lithium secondary battery for each of the IC chips is connected as a most downstream power source configured to a power source voltage level required for the IC chip, whereby electric power is individually distributed and supplied to the plurality of IC chips from the plurality of all-solid-state lithium secondary batteries;
• and
• wherein the IC substrate with a mounted secondary battery further comprising a battery controller that supplies a peak current from the all-solid-state lithium secondary battery to the IC chips to respond to instantaneous high load operation of the IC chips and charges the all-solid-state lithium secondary battery after completion of the high-load operation.
