Abstract
A computer includes: a memristor array including memristors arranged at intersections between word lines and a first bit line in the memristor array and at intersections between the word lines and second bit lines in the memristor array; an adder circuit configured to obtain sum voltages for the second bit lines by adding first voltages generated according to currents that flow in the second bit lines when a first pattern is supplied to the word lines to difference voltages between a reference voltage generated according to a current that flows in the first bit line when a second pattern is supplied to the word lines and second voltages generated according to currents that flow in the second bit lines when a second pattern is supplied to the word lines; and a detection circuit that detects a second bit line that corresponds to a maximum value of the sum voltages.
