The Chapters
-
· assimilaate · memristors · ai-hardware · edge-ai
Chapter 1: Transforms will be Assimilated
Ship synapses. Stream transforms. Forget weights.
-
· memristors · ahah-plasticity · knowm-history · darpa-synapse
Chapter 2: Before I Knew of the Word Memristor
Twenty-five years assembling the synaptic solution.
-
· thermodynamic-computing · kt-bit · self-organization · physical-intelligence
Chapter 3: The Thermodynamic Bit
Nature builds with one primitive, at every scale, and you've stared at it your whole life without actually seeing it.
-
· memristors · kt-ram · ai-hardware · differential-pair · emulator · open-source
Chapter 3b: The Thermodynamic Bit, Derived
Store a weight in two memristors instead of N bits, and optimal annealing, Bayesian inference, and native probabilistic sampling become a property of matter.
-
· memristors · eda · layout · knowm-history · ai-hardware
Chapter 3c: The Thermodynamic Bit, Built
Simulate a memristor synapse, draw it polygon by polygon, and send it to the fab — the part of building neuromorphic hardware where a circuit idea becomes silicon.
-
· memristors · kt-ram · ai-hardware · crossbars
Chapter 4: The Neural Lane
kT-RAM is the genus. The neural lane is a species.
-
· memristors · kt-ram · ai-hardware · differential-pair · emulator · open-source
Chapter 4b: The Neural Lane Emulator
An open Python emulator of the 2-1 neural lane — its object model and instruction set — checked on a single synapse against the Chapter 3b physics: inertia, evidence-counting, and the read as a thermal sample.
-
· memristors · kt-ram · ai-hardware · unsupervised-learning · ahah · emulator · open-source
Chapter 5: Thermodynamic Logic Gates
When two kT-bits interact on a neural lane under the FF-RU kT-RAM instruction set, attractor states emerge that we identify as logic functions.
-
· memristors · kt-ram · ai-hardware · unsupervised-learning · ahah · support-vectors · emulator · open-source
Chapter 5b: Maximizing Noise Margin
An unsupervised AHaH boundary settles where the data points push on the decision line all balance. The nearest points are its support vectors, and the gap they hold open is a noise margin against thermal and read noise.
-
· memristors · kt-ram · ai-hardware · supervised-learning · classifier · thermodynamic-computing · generative · sampling · emulator · open-source
Chapter 6: Classification and Thermal Sampling on kT-RAM Neural Lanes
We teach neural lanes to classify labelled data. They learn one example at a time and land on the same accuracy as logistic regression. Then we teach fresh lanes the opposite mapping and read them at temperature: clamp a label, draw a sample.
-
· memristors · kt-ram · ai-hardware · unsupervised-learning · basis-encoder · vector-quantization · generative · emulator · open-source
Chapter 6b: The Unsupervised Basis Encoder
Learn a codebook with no answer key, provided you limit the run-away positive feedback where the rich get richer. We build and train our first multi-module kT-RAM network, a binarized fashion MNIST encoder/decoder/classifier with thermal sampling.

How 374 Papers Build a Signed Synaptic Weight
A memristor's conductance can't go negative, but a synaptic weight must. I surveyed 374 papers on how the field gets around that — one device, two, or many — and almost everyone reads the weight as a difference.

A Decade of Knowm SDC Memristor Literature, Part 2
What people actually built with Knowm's Self-Directed Channel memristor — the applications, sorted, and the strange ones.

The kT-bit Reading List
The thinkers — a chemist, a physicist, a systems theorist, an ecologist, a roboticist — who circled the same primitive the kT-bit names, and where to find their work.
