3d neuromorphic system and operating method thereof

Abstract

Disclosed is a technology of independently connecting a plurality of neuromorphic elements three-dimensionally laminated on a Complementary Metal-Oxide Semiconductor (CMOS) wafer through an interconnection layer and selectively driving and testing the plural neuromorphic elements with pulses generated and transmitted from the CMOS wafer. More particularly, the 3D neuromorphic system implemented on a Complementary Metal-Oxide Semiconductor (CMOS) wafer, the 3D neuromorphic system including: an element array including a plurality of neuromorphic elements respectively and independently connected to a plurality of interconnection layers formed on the Complementary Metal-Oxide Semiconductor (CMOS) wafer; a synaptic pulse generator configured to generate at least one synaptic pulse to generate synaptic characteristics in the plural neuromorphic elements; and a controller configured to generate a control signal for controlling generation of the at least one synaptic pulse and to control the at least one synaptic pulse generated in the plural neuromorphic elements to sequentially applied.
