1. A neuromorphic device comprising:
an electrode including a first terminal connected to a bit line through a write drive transistor and a second terminal connected to a source line;
a plurality of unit weighting elements having different resistance values, each of the plurality of unit weighting elements comprising a free layer arranged on the top of the electrode, a tunnel barrier layer arranged on the top of the free layer, and a fixed layer arranged on the top of the tunnel barrier layer, and corresponding to each bit of a synapse weight; and
a plurality of control electrodes connected to the bit line through a plurality of read drive transistors, respectively, a control voltage being applied between the free layer and the fixed layer of each of the plurality of unit weighting elements through each of the plurality of control electrodes.
