Analog Memristive Synapse in Spiking Networks Implementing Unsupervised Learning
Emerging brain-inspired architectures call for devices that can emulate the functionality of biological synapses in order to implement new efficient computational schemes able to solve ill-posed problems. Various devices and solutions are still under investigation and, in this respect, a challenge is opened to the researchers in the field. Indeed, the optimal candidate is a device able to repro...
متن کاملAnalog-to-Digital and Digital-to-Analog Conversion with Memristive Devices
We suggest a novel methodology to obtain a digital representation of analog signals and to perform its backconversion using memristive devices. In the proposed converters, the same memristive systems are used for two purposes: as elements performing conversion and elements storing the code. This approach to conversion is particularly relevant for interfacing analog signals with memristive digit...
متن کاملAdvancing Memristive Analog Neuromorphic Networks: Increasing Complexity, and Coping with Imperfect Hardware Components
Abstract We experimentally demonstrate classification of 4×4 binary images into 4 classes, using a 3-layer mixedsignal neuromorphic network (“MLP perceptron”), based on two passive 20×20 memristive crossbar arrays, boardintegrated with discrete CMOS components. The network features 10 hidden-layer and 4 output-layer analog CMOS neurons and 428 metal-oxide memristors, i.e. is almost an order of ...
متن کامل“Modeling Memristive Biosensors”
In the present work, a computational study is carried out investigating the relationship between the biosensing and the electrical characteristics of two-terminal Schottkybarrier silicon nanowire devices. The model suggested successfully reproduces computationally the experimentally obtained electrical behavior of the devices prior to and after the surface bio-modification. Throughout modeling ...
متن کاملSpin memristive systems
Recently, in addition to the well-known resistor, capacitor and inductor, a fourth passive circuit element, named memristor, has been identified following theoretical predictions. The model example used in such case consisted in a nanoscale system with coupled ionic and electronic transport. Here, we discuss a system whose memristive behaviour is based entirely on the electron spin degree of fr...
