A

biasing method for programming of nonlinear

memristor-based neural networks is addressed in this

paper. Weights of neural networks are designed based on

Memristor Bridge Synapse. Despite many significant benefits

of the memristor bridge synapse, there is one critical

weakness that programming at its extreme (max or min)

states is nonlinear due to boundary effects of memristors,

which is common in most of nano-devices. It is an important

issue when a neural network is to be programmed or a

learned neural network is to be reproduced for multiple

copies. In this study, a novel architecture of a modified

memristor bridge synapse is also proposed. In the modified

architecture of the Memristor Bridge Synapse in which two

switches are added for initialization and programming of the

synapse, the boundary effect issue is avoided by biasing the

Programming Origin to the middle of linear region.
