Boolean Logic Gates From A Single Memristor Via Low-Level Sequential Logic
Ella Gale, Ben de Lacy Costello, Andrew Adamatzky
By using the memristor's memory to both store a bit and perform an operation with a second input bit, simple Boolean logic gates have been built with a single memristor. The operat…
Is Spiking Logic the Route to Memristor-Based Computers?
Ella Gale, Ben de Lacy Costello, Andrew Adamatzky
Memristors have been suggested as a novel route to neuromorphic computing based on the similarity between neurons (synapses and ion pumps) and memristors. The D.C. action of the me…
The Short-term Memory (D.C. Response) of the Memristor Demonstrates the Causes of the Memristor Frequency Effect
Ella Gale, Ben de Lacy Costello, Victor Erokhin +1
A memristor is often identified by showing its distinctive pinched hysteresis curve and testing for the effect of frequency. The hysteresis size should relate to frequency and shri…
Does the D.C. Response of Memristors Allow Robotic Short-Term Memory and a Possible Route to Artificial Time Perception?
Ella Gale, Ben de Lacy Costello, Andrew Adamatzky
Time perception is essential for task switching, and in the mammalian brain appears alongside other processes. Memristors are electronic components used as synapses and as models f…
Design of a Hybrid Robot Control System using Memristor-Model and Ant-Inspired Based Information Transfer Protocols
