Abstract
A multiply-accumulate calculation device includes: multiple calculation units which generates output signals by multiplying an input signal corresponding to an input value and having a rising part, a signal part, and a falling part by a weight, and output the output signals; an accumulate calculation unit configured to calculate a sum of the output signals output from the plurality of multiple calculation units; and a correction unit configured to execute correction processing for correcting the sum of the output signals on the basis of a correction value including at least one of a first value incorporated into the sum by a current flowing into variable resistors of the multiple calculation units due to the rising part of the input signal, and a second value incorporated into the sum by a current flowing into the variable resistors of the multiple calculation units due to the falling part of the input signal.
