The problem

Brains store memories by strengthening synapses that fire together. A memristor remembers the last current through it, which makes it a natural candidate for an artificial synapse.

How it works

  1. 1Studied how memristors map onto spiking, multilayer, convolutional and recurrent neural networks
  2. 2Built a threshold type memristor emulator circuit
  3. 3Simulated it in PSpice with a 2.5 V, 5 Hz sine input

Result

The simulation showed the memristor behaviour that lets it act as a synapse in a neural network.
