Title:
ニューラルネットワーク回路
Document Type and Number:
Japanese Patent JP6756287
Kind Code:
B2
Abstract:
A neural network circuit includes a memory device in which memristors being variable resistance elements are connected in a matrix and serve as memory elements of the memory device. The neural network circuit further includes a voltage application device arranged to apply a bias voltage to the memory device and current-voltage (I-V) conversion amplification circuits arranged to convert currents flowing via the memory elements into voltages and output the voltage. A feedback resistor of a respective I-V conversion amplification circuit includes a memristor. The feedback resistor of a respective I-V conversion amplification circuit and the memory elements acting as an input resistor of the I-V conversion amplification circuit are connected to align a polarity direction of the memristor of the feedback resistor and polarity directions of the memristors of the memory elements acting as the input resistor.
