Speech Title: High-Performance Chalcogenide-based Phase-Change Memory Technology
Abstract: We have entered into an unprecedented era of IoT and high-performance memories are required to store explosively growing information. Although currently flash memory is still the mainstream nonvolatile memory, it is facing many serious problems such as slow speed, and bad endurance. Phase-change memory (PCM) is widely regarded as the next generation nonvolatile memory. It is based on rapid reversible phase-transformation between amorphous and crystalline phases of chalcogenide such as Ge2Sb2Te5. In this invited talk, the following contents will be covered. 1. chalcogenide with low volume change for high reliability, 2. PCM with more than 8 resistance levels for high storage density, 3. PCM with nanostructures for low power consumption.
