Materials that can rapidly switch from crystal to glass are appealing for use in computer memory devices. However, the challenge is making that switch rapid enough to compete with current memory options. Loke et al. used a one-time electric precursor pulse designed to condition a traditional phase-change material for rapid switching. This method dramatically improved the switching speed, allowing them to create a phase-change memory that is ultrafast and highly stable.
