Abstract
Recent discovery (2008) of the non-volatile binary resistances known as memristors has attracted new scientific research opportunities. These include novel approaches to present-day technology such as memory storage, computer architectures and hardware security. In this project, the physical feasibility of gates using stateful logic will be experimentally tested to understand surging problems in the design procedure. The gate being built will aim to perform material implication logic. These memristor-based logic circuits form the building blocks of crossbar array architectures, a computer architecture developed currently that would simultaneously perform processing operations and memory storage. Throughout this project, the commercially available memristors provided by Knowm will be characterized. The essential traits of the memristors will be tested for a DC voltage sweep experiment and a voltage pulse analysis will be performed using pulses with a width of 2 ms. The analysis will be explained presenting case-to-case behavior as well as statistical data from up to 200 experiments. Building upon this knowledge, the IMPLY gate was made and showed problems indicated by previous research studies, like state drift. This project serves also as an introduction to memristive technology.
