Researchers at the Korea Advanced Institute of Science and Technology (KAIST) used three-dimensional imaging to map a nanoscale current pathway inside a capacitor for a resistive random-access memory (RRAM) device. They found that it connected to a tiny protrusion on the bottom electrode. The finding suggests that shaping the electrode could help control where these pathways form.
