Artificial neuron device and neuromorphic system

摘要

To realize an efficient artificial neuron specifically. An artificial neuron device includes a resistive memory cell connected in an input circuit having a neuron input for receiving a neuron input signal, and a current source for supplying a read current to the cell. . The input circuit is responsive to a set of control signals defining alternating read and write operation phases to apply a read current to the cell during the read phase and to receive cell resistance when receiving the neuron input signal during the write phase. Can be selectively configured to apply a programming current to the cell to program the. The cell resistance is progressively changed from the first state to the second state in response to the continuous neuron input signal. The apparatus further includes an output circuit that includes a neuron output and a digital latch connected to the input circuit to receive a measurement signal that is dependent on cell resistance.
