Neuromorphic synaptic device, neuromorphic system and method of manufacturing neuromorphic synaptic device (neuromorphic synapse)

摘要

To provide a method for manufacturing a neuromorphic synapse device, a neuromorphic system and a neuromorphic synapse device.A neuromorphic synapse device includes a mem element and a programming logic for storing synapse loads. MEM element 20 is made to exhibit desired programming characteristics. The programming logic 21 responds to a stimulus that prompts a renewal of the synapse load and generates a programming signal for programming the mememelement 20 to update the load. The programming logic 21 calculates the input load change value W_iIn response to the input load change value W_iTo generate a programming signal that is dependent on. The programming logic 21 is adapted to take advantage of the programming characteristics of the mem element 20 so that the programming signal provides the desired load dependent synapse update effect.(FIG.
