Product-sum operation unit, logic operation device, neuromorphic device and product-sum operation method

摘要

The product-sum operation unit corresponds to an input value, multiplies an input signal having a rising portion, a signal portion, and a falling portion by a weight to generate an output signal, and outputs the output signal, and a plurality of product operation portions A sum operation unit that calculates the sum of the output signals output from each of the plurality of product operation units; and the sum due to a current flowing into variable resistors of the plurality of product operation units due to the rising portion of the input signal A correction value including at least one of a second value to be incorporated into the sum by the current flowing into the variable resistors of the plurality of product operation units due to the first value incorporated into the first signal and the falling portion of the input signal And a correction unit that executes a correction process that corrects the total sum of the output signals on the basis of the above.
