An electronic circuit for which a coil 22 is disposed overlapping with a memory array region to carry out communications by inductive coupling between stacked and mounted chips by the coil 22. Because intersections 1 and 2 between the coil 22 and a bit line 15 are located at a pair of positions that are equal to each other in wiring length from both terminals a and g of the coil 22, interference from the bit line 15 to the coil 22 results in the same phase and same amplitude at both ends of the coil 22, and can thus be eliminated by a differential amplifier. Thereby, a coil antenna can be disposed so that, even when a coil antenna to carry out communications by inductive coupling is disposed overlapping with a memory array region, little interference occurs from a memory array wiring to communications by the coil antenna. |
