Abstract
According to one embodiment, a semiconductor memory device includes a memory cell including a transistor formed of an oxide semiconductor, an insulation film, and a control electrode, and a capacitance element configured to store a charge, the memory cell being configured to store a coupling weight of a neuron model by a charge amount accumulated in the capacitance element; and a control circuit configured to output a signal as a sum of a product between input data of the memory cell and the coupling weight.
