Abstract
A three-dimensional integrated circuit includes a plurality of perpendicular stacked chips. Each chip of the plurality of perpendicular stacked chips includes at least one transistor, a sensing coil, and a magnetic sensor, wherein the magnetic sensor is installed above the at least one transistor and the sensing coil and the sensing coil is installed between the magnetic sensor and the at least one transistor. The chip utilizes the sensing coil to generate a magnetic field including data, and a first chip of the plurality of perpendicular stacked chips adjacent to the chip utilizes a magnetic sensor of the first chip to receive the data generated by the sensing coil of the chip through the magnetic field generated by the sensing coil of the chip.
