SYNAPSE ARRAY OF NEUROMORPHIC DEVICE INCLUDING SYNAPSES HAVING FERRO-ELECTRIC FIELD EFFECT TRANSISTORS AND OPERATION METHOD OF THE SAME

摘要

A synapse array of a neuromorphic device is provided. The synapse array may include a pre-synaptic neuron; a row line extending from the pre-synaptic neuron in a row direction; a post synaptic neuron; a column line extending from the post-synaptic neuron in a column direction; and a synapse disposed at an intersection region between the row line and the column line. The synapse may include an n-type ferroelectric field effect transistor (n-FeFET) having a source electrode, a gate electrode and a body; a p-type ferroelectric field effect transistor (p-FeFET) having a source electrode, a gate electrode and a body; and a resistive element having a first node electrically connected to the source electrode of the n-FeFET and electrically connected to the source electrode of the p-FeFET, and the n-FeFET and the p-FeFET are electrically connected in series.
