With Harvard Researchers, Samsung introduces a brand new method to reverse engineer the mind on a reminiscence chip, in a Perspective paper revealed in Nature Electronics
Samsung Electronics, a world chief in superior semiconductor expertise, as we speak shared a brand new perception that takes the world a step nearer to realizing neuromorphic chips that may higher mimic the mind.
Envisioned by the main engineers and students from Samsung and Harvard University, the perception was revealed as a Perspective paper, titled ‘Neuromorphic electronics based on copying and pasting the brain’, by Nature Electronics. Donhee Ham, Fellow of Samsung Advanced Institute of Technology (SAIT) and Professor of Harvard University, Professor Hongkun Park of Harvard University, Sungwoo Hwang, President and CEO of Samsung SDS and former Head of SAIT, and Kinam Kim, Vice Chairman and CEO of Samsung Electronics are the co-corresponding authors.

The essence of the imaginative and prescient put ahead by the authors is greatest summed up by the 2 phrases, ‘copy’ and ‘paste’. The paper suggests a option to copy the mind’s neuronal connection map utilizing a breakthrough nanoelectrode array developed by Dr. Ham and Dr. Park, and to stick this map onto a high-density three-dimensional community of solid-state recollections, the expertise for which Samsung has been a world chief.
Through this copy and paste method, the authors envision to create a reminiscence chip that approximates the distinctive computing traits of the mind – low energy, facile studying, adaptation to surroundings, and even autonomy and cognition – which have been past the attain of present expertise.
The mind is made up of a lot of neurons, and their wiring map is accountable for the mind’s capabilities. Thus the data of the map is the important thing to reverse engineering the mind.
While the unique objective of neuromorphic engineering, launched within the 1980s, was to imitate such construction and performance of the neuronal networks on a silicon chip, it proved troublesome as a result of, even till now, little is thought of how the massive variety of neurons are wired collectively to create the mind’s increased capabilities. Thus, the objective of neuromorphic engineering has been eased to designing a chip ‘inspired’ by the mind somewhat than rigorously mimicking it.
This paper suggests a option to return to the unique neuromorphic objective of the mind reverse engineering. The nanoelectrode array can successfully enter a lot of neurons so it might probably report their electrical indicators with excessive sensitivity. These massively parallel intracellular recordings inform the neuronal wiring map, indicating the place neurons join with each other and the way sturdy these connections are. Hence from these telltale recordings, the neuronal wiring map could be extracted, or ‘copied’.
The copied neuronal map can then be ‘pasted’ to a community of non-volatile recollections – akin to industrial flash recollections which are utilized in our on a regular basis life in solid-state drives (SSD), or ‘new’ recollections akin to resistive random entry recollections (RRAM) – by programming every reminiscence in order that its conductance represents the energy of every neuronal connection within the copied map.

The paper takes a step additional and suggests a technique to quickly paste the neuronal wiring map onto a reminiscence community. A community of specially-engineered non-volatile recollections can be taught and categorical the neuronal connection map, when instantly pushed by the intracellularly recorded indicators. This is a scheme that instantly downloads the mind’s neuronal…
