Abstract
The objective of the invention is to provide technology allowing data taking a plurality of values to be transmitted and received using one set of coils when sending data through TCI technology using magnetic field coupling. This layered semiconductor device has at least a first semiconductor chip and a second semiconductor chip layered therein, the first semiconductor chip transmitting data in a contactless manner, and the second semiconductor chip receiving, in a contactless manner, the data that has been transmitted. The first semiconductor chip contains: a transmission unit outputting a transmission signal that may acquire, on the basis of the value of the data to be sent, at least 3 types of states representing the value of the data; and a transmission coil converting the transmission signal into a magnetic field signal. The second semiconductor chip contains: a reception coil whereby the magnetic field signal converted by the transmission coil is converted into a reception signal; and a reception unit reconstructing, on the basis of the state of the reception signal, the data that has been transmitted.
