Overview

The Knowm technology stack bridges the levels of abstraction required to realize an AI processor based on memristor synapses, connecting the dots from nanotechnology to applications.

Memristors are an enabling nanotechnology for a new AI computing technology stack

Knowm M-SDC memristors have openly demonstrated all physical properties required of our technology stack, including the important manufacturing properties of low cost, high yields and long shelf-life.

A collection of synaptic elements form neuron-like computing circuits

Learning/programming and logic/inference operations reduce to the activation of a low-voltage analog circuit, eliminating memory-processing communication, improving speed and greatly reducing energy dissipation.

Information is encoded by integer tensor streams

A spike stream is a temporal sequence of spike patterns. A spike pattern is a collection of integers in a defined spike space. A spike tensor is a multi-dimensional array of spike streams.

Synaptic cores are collections of synapses that are partitioned into one or more neurons

Collections of addressable differential-pair memristor synapses form the primitive mixed memory-processing core from which learning/programming and inference/logic operations are realized. Many core types are possible based on synaptic addressing method and topology restrictions. Cores can be emulated by existing computing technology.

Example Synaptic Core Types

Example synaptic core types

Synaptic cores execute instructions on co-activated synaptic elements

Elemental instructions define electrical drive patterns across the terminals of co-activated memristor synapses. These instructions can result in modification of the synaptic state and are used for both learning/programming and inference/logic operations. Different underlying synapse circuits (1-2, 2-1, 1-2i, 2-1i) require different drive patterns to achieve the same functional effect, for example to increment the synaptic state high or low, decay its magnitude, etc.
