The realization of non-volatile working memory is a dream in the LSI field. However, non-volatility requires a large amount of energy to write data and no non-volatile memory has been used as working memory. New spintronics writing mechanisms, STT, Spin-Hall, and VoCSM have been studied. It has been concluded that Spin-Hall writing and VoCSM writing have non-volatility, reasonably small energy consumption, and practically unlimited endurance.
Further efforts in physics and engineering may realize the dream in a few years.
