Abstract
To provide a product-sum calculation device that includes a plurality of synapses including a transistor and having a variable resistance value, a plurality of input lines extending in a first direction and that propagates an input signal to each of the plurality of synapses, a plurality of output lines extending in a second direction orthogonal to the first direction, and that outputs a product-sum calculation result of the input signal from each of the plurality of synapses, and a charge and discharge control unit that controls an output state of the product-sum calculation result by controlling a charge and discharge state of the output line on the basis of a polarity of the transistor.
