Multi Valued Logic Using Ferroelectric Perovskites

Multi valued logic is the way the real world works, in shades of gray. We call this “analog” states and this kind of logic becomes complex. In order to simplify it, we abstract simple black and white logic conditions, also known as digital or binary states. Almost all of our computing and electronic resources use binary states for both memory and calculations.

Our brains use analog or multi valued logic in the electro-chemical states of neural synapses. In our quest to create computers that operate in a manner similar to our brains, we try to mimic this process, but it is not easy to accomplish with our primitive electronic components. We need more advanced electronics that work in an analog fashion.

Perovskites are mainly known for their solar photovoltaic potential, but a thin film version of them may present new opportunities for constructing “multi-bit” electronic components using their stable polarization states.

New study of ferroelectrics offers roadmap to multivalued logic for neuromorphic computing – []

Research published Wednesday in Nature Scientific Reports lays out a theoretical map to use ferroelectric material to process information using multivalued logic – a leap beyond the simple ones and zeroes that make up our current computing systems that could let us process information much more efficiently.

The language of computers is written in just two symbols – ones and zeroes, meaning yes or no. But a world of richer possibilities awaits us if we could expand to three or more values, so that the same physical switch could encode much more information.
