Abstract
There are disclosed herein various implementations of semiconductor packages having an interposer configured for magnetic signaling. One exemplary implementation includes a die transmit pad in an active die for transmitting a magnetic signal corresponding to a die electrical signal produced by the active die, and an interposer magnetic tunnel junction (MTJ) pad in the interposer for receiving the magnetic signal. A sensing circuit is coupled to the interposer MTJ pad for producing a receive electrical signal corresponding to the magnetic signal. In one implementation, the sensing circuit is configured to sense a resistance of the interposer MTJ pad and to produce the receive electrical signal according to the sensed resistance.
