Abstract
An electronic apparatus includes a first circuit board, a stacked circuit that is provided on the first circuit board through first coupling terminals and has a structure in which arithmetic elements and memory elements are stacked through inter-element coupling terminals and to which a signal is inputted from the first circuit board, and a second circuit board that is provided on the stacked circuit through second coupling terminals and to which a result of processing is outputted from the stacked circuit, wherein a number of the first coupling terminals and a number of the second coupling terminals are smaller than that of the inter-element coupling terminals.
