In Proceedings of the 18th International Conference on Parallel Architectures and Compilation Techniques. Phase-change memory (PCM) is considered a storage-class memory that fits between DRAM and NAND in the memory hierarchy. Phase-change memory (PCM) exploits the behavior of so-called phase-change materials that can be switched reversibly between amorphous and crystalline phases of different electrical resistivity. Phasenwechselspeicher, Phase Change Memory (PCM), sind nichtflüchtige Speicher, die auf der Änderung des elektrischen Widerstands des Speichermaterials basieren. The amorphous phase tends to have high electrical resistivity, whereas the crystalline phase exhibits a low resistivity, sometimes three or four orders of magnitude lower. Doch die Kontrolle der Phasenänderungen von einem amorphen in einen kristallinen Zustand mit der nötigen Präzision und … DOI: 10.1016/j.tsf.2016.05.042.

Phase Change Memory (PCM) hat als einzige der alternativen nichtflüchtigen Speichertechniken das Potenzial, einen breiteren Markt zu erreichen. Recently, new memory technologies, called ReRAM (e.g., phase change memory—PCM, spin-transfer torque magnetic memory—STT-MRAM, metal oxide resistive switching memory—OxRAM, conductive-bridge memory—CBRAM, and vertical resistive memories—VRAM) have appeared [21, 22]. Atwood, Gregory. Thin Solid Films 2016, 612, 135-140. Also, since code may be executed directly from memory rather than being copied into RAM, PCM operates faster. Pages 223-262. PCM Applications and an Outlook to the Future. PCM Array Architecture and Management. A key advantage of phase change technology, first explored by Hewlett Packard, is that the memory state does not require continuous power to remain stable. Global Market Phase Change Memory Average Price (USD/Unit) of Key Manufacturers in 2019 Figure 22. Villa, Corrado. Phase change memory is based on a technique known as the memresitor that was initially developed by Hewlett Packard.

Pages 285-311. The addition of data in PCM does not require an erase cycle, typical of other types of memory storage. Die Speichertechnik könnte Flash-Speicher ersetzen, lassen sich damit doch Phase change memory uses a semiconductor alloy that can be changed rapidly between an ordered, crystalline phase having lower electrical resistance to a disordered, amorphous phase with much higher electrical resistance. Because no electrical power is required to maintain either phase of the material, so phase-change memory is non-volatile. Although the device physics related to the operation of PCM have been widely studied since its … 50 years after the discovery of phase change memory (PCM) it makes sense a look that bundles together a retrospective gaze to rebuild its history, both from a technology and products development point of view, with the opportunities of PCM for new applications looking to the future.
