NEUROMORPHIC CHIP FOR UPDATING PRECISE SYNAPTIC WEIGHT VALUES - A simplified explanation of the abstract

This abstract first appeared for US patent application 18366348 titled 'NEUROMORPHIC CHIP FOR UPDATING PRECISE SYNAPTIC WEIGHT VALUES

Simplified Explanation

The patent application describes a neuromorphic chip design that includes synaptic cells, resistive devices, axon lines, dendrite lines, and switches.

• The chip has a crossbar array formed by connecting the synaptic cells to the axon and dendrite lines.
• The axon lines receive input data and supply it to the synaptic cells.
• The dendrite lines receive output data and supply it through output lines.
• The switches connect input terminals to input lines and can changeably connect output terminals to axon lines.

Original Abstract Submitted

A neuromorphic chip includes synaptic cells including respective resistive devices, axon lines, dendrite lines and switches. The synaptic cells are connected to the axon lines and dendrite lines to form a crossbar array. The axon lines are configured to receive input data and to supply the input data to the synaptic cells. The dendrite lines are configured to receive output data and to supply the output data via one or more respective output lines. A given one of the switches is configured to connect an input terminal to one or more input lines and to changeably connect its one or more output terminals to a given one or more axon lines.
