We experimentally demonstrated a magnetic tunnel junction (MTJ) based circuit that allows direct communication between elements without intermediate sensing amplifiers. The input of the circuit consists of three MTJs connected in parallel. The direct communication is realized by connecting the output in series with the input and applying voltage across the series connections. Combining the circuit with complementary metal oxide semiconductor current mirrors allows for fan-out to multiple outputs. The change in resistance at the input resulted in a voltage swing across the output of 150-200 mV for the closest input states which is sufficient to realize all of the Boolean primitives.
