Phase Change Materials Increase the Speed Limit for Computers

By replacing silicon with phase-change materials, new research shows that computers could be capable of processing information up to 1,000 times faster than currently models. The present size and speed limitations of computer processors and memory could be overcome by replacing silicon with ‘phase-change materials’ (PCMs), which are capable of reversibly switching between two structural […]
