Abstract

Ovonic unified memory (OUM) is an advanced memory technology that uses a chalcogenide alloy (GeSbTe).The alloy has two states: a high resistance amorphous state and a low resistance polycrystalline state. These states are used for the representation of reset and set states respectively. The performance and attributes of the memory make it an attractive alternative to flash memory and potentially competitive with the existing non volatile memory technology.

“Ovonic Unified Memory” is the registered name for the non-volatile memory based on the material called chalcogenide.

The term “chalcogen” refers to the Group VI elements of the periodic table. “Chalcogenide” refers to alloys containing at least one of these elements such as the alloy of germanium, antimony, and tellurium discussed here. Energy Conversion Devices, Inc. has used this particular alloy to develop a phase-change memory technology used in commercially available rewriteable CD and DVD disks. This phase change technol ....etc

ABSTRACT
Nowadays, digital memories are used in each and every fields of day-to-day life. Semiconductors form the fundamental building blocks of the modern electronic world providing the brains and the memory of products all around us from washing machines to super computers. But now we are entering an era of material limited scaling. Continuous scaling has required the introduction of new materials.
Current memory technologies have a lot of limitations. The new memory techno ....etc
