1. A semiconductor device comprising:
variable resistance elements on a semiconductor substrate, wherein
each of the variable resistance elements includes a first electrode, a second electrode, and a variable resistance layer that is sandwiched between the first electrode and the second electrode and that stores a resistance value that is continuously variable,
the variable resistance layer includes a filament whose shape differs according to a neural network weight, and stores, as an analog value, the resistance value that is variable, and
an area of the filament in a plan view of the semiconductor substrate differs according to the neural network weight.
