Can conventional phase-change memory devices be scaled down to single-nanometre dimensions?

Projected phase-change memory devices

Nanoscale memory devices, whose resistance depends on the history of the electric signals applied, could become critical building blocks in new computing paradigms, such as brain-inspired computing and memcomputing. However, there are key challenges to overcome, such as the high programming power required, noise and resistance drift. Here, to address these, we present the concept of a projected...

Single Layer Centrifugation Can Be Scaled-Up Further to Process up to 150 mL Semen

Single-Layer centrifugation has been used to improve the quality of sperm samples in several species. However, where stallion or boar semen is to be used for AI, larger volumes of semen have to be processed than for other species, thus limiting the effectiveness of the original technique. The objective of the present study was to scale up the SLC method for both stallion and boar semen. Stallio...

A Single Element Phase Change Memory

We report a fast single element nonvolatile memory that employs amorphous to crystalline phase change. Temperature change is induced within a single electronic element in confined geometry transistors to cause the phase change. This novel phase change memory (PCM) operates without the need for charge transport through insulator films for charge storage in a floating gate. GeSbTe (GST) was emplo...
