1. A synaptic module of a neuromorphic apparatus having a three-dimensionally-stacked synaptic structure, the synaptic module comprising:
a first word line;
a first memory cell comprising a first metal disposed on the first word line, a ferroelectric disposed on the first metal, an insulator disposed on the ferroelectric, and a second metal disposed on the insulator;
a bit line is disposed on the second metal of the first memory cell;
a second memory cell comprising a second metal disposed on the bit line, an insulator disposed on the second metal of the second memory cell, a ferroelectric disposed on the insulator of the second memory cell, and a first metal disposed on the ferroelectric of the second memory cell; and
a second word line is disposed on the first metal of the second memory cell,
wherein the second metal, the insulator, the ferroelectric, and the first metal of the second memory cell are arranged sequentially in a direction from the bit line to the second word line, in an order of the second metal, the insulator, the ferroelectric, and the first metal.
