Abstract

Disclosed is a binarized neural network circuitry using a quasi-nonvolatile memory device. More particularly, the binarized neural network circuitry according to an embodiment of the present disclosure is characterized in that a diode structure is positioned in a channel region between a drain terminal and a source terminal, a gate terminal is positioned on the diode structure, an operation state is determined by occurrence of a latch-up or latch-down phenomenon due to a positive feedback loop in the channel region based on different voltages applied to the drain terminal and the gate terminal, respectively, and a plurality of quasi-nonvolatile memory devices that implement memory characteristics of remembering a memory state are included as holes or electrons in a potential well in the channel region due to the positive feedback loop are accumulated, and the plural quasi-nonvolatile memory devices are a pair of two quasi-nonvolatile memory devices that operate as a single synaptic cell and are connected in parallel to form an array circuit, memory states of the two quasi-nonvolatile memory devices are determined and stored based on an input line applied from an input line processor connected to the array circuit and a weight update signal applied from a synaptic line processor connected to the array circuit, and a MAC (multiply-accumulate) operation result is output using a combination of the memory states.
