Title:
NEURAL NETWORK ARITHMETIC CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2023/171683
Kind Code:
A1
Abstract:
This neural network arithmetic circuit holds a plurality of coupling weight coefficients corresponding respectively to a plurality of input data pieces, and outputs output data in accordance with the results of product-sum operations between the plurality of input data pieces and the corresponding coupling weight coefficients, wherein: the neural network arithmetic circuit comprises at least two bits of semiconductor storage elements, namely a variable resistance element (RPA0) and a variable resistance element (RPB0) for storing the coupling weight coefficients; and each of the plurality of coupling weight coefficients corresponds to a total current value obtained by adding a current value for the current flowing through the variable resistance element (RPA0) and a current value for the current flowing through the variable resistance element (RPB0).
