  Functional materials can offer new paradigms for miniaturized and
energy-efficient electronics, providing a complementary or even alternative
platform to metal-oxide-semiconductors. Here we report on electronically
accessible long-lived structural states in Vanadium Dioxide that can offer a
scheme for data storage and processing. We show that such states can be
electrically manipulated and tracked beyond 10,000 seconds after excitation,
exhibiting similar features of glasses, which are beyond the classic
metastability in Mott systems. Glass-like electronics can potentially overcome
some of the fundamental limitations in conventional metal-oxide-semiconductor
electronics, and open avenues for neuromorphic computation and multi-level
memories.
