Samenvatting

The article discusses the prospects of non-linear memristors as the missing core hardware element for neuromorphic computers, which can overcome the limitations of traditional von-Neumann architecture.
Key highlights:

The energy consumption of information and communications technologies (ICT) is expected to rise significantly due to the continuous data transfer between separated memory and processor units.
Neuromorphic computers with merged memory and processor units can circumvent this issue, but the core hardware element has not been realized so far.
Non-linear memristors, unlike linear memristors, can serve as both memory and processor in the same device without data transfer, enabling resource-saving neuromorphic computing.
Non-linear memristors have unique properties, such as analog resistance changes and the ability to read and write data in the same device, which make them suitable for this purpose.
The article analyzes the current-voltage characteristics and flux-charge curves of linear and non-linear memristors to understand their differences and the advantages of non-linear memristors for neuromorphic computing.
The author's own contributions in developing the BiFeO3-based non-linear memristor are discussed, highlighting its potential as the core hardware element for neuromorphic computers.
The future implications of non-linear memristors are explored, including their ability to perform computations of transcendental functions in a single time step, which could lead to the development of new computational models.

"Only memristors with non-linear I-V curves [3] have been shown to be able to process and store data in the same device [4], thus fulfilling the requirements of the so far missing core hardware for resource-saving neuromorphic computers."
"Because non-linear memristor devices are expected to perform computing of input-output maps of transcendental functions in a single time step, it is proposed to incorporate non-linear memristor devices as registers in neuromorphic computers that can compute transcendental, e.g. exponential or logarithmic, functions over reals in a single time step."
