Phase change memory (PCM) is a rapidly growing technology that not only offers advancements in storage-class memories but also enables in-memory data storage and … This book describes the physics of phase change memory devices, starting from basic operation to reliability issues. Download PDF Abstract: We survey the current state of phase change memory (PCM), a non-volatile solid-state memory technology built around the large electrical contrast between the highly-resistive amorphous and highly-conductive crystalline states in so-called phase change materials. Authors: Vinay Joshi, Manuel Le Gallo, Simon Haefeli, Irem Boybat, S.R. Abstract: Phase-change memory (PCM) has undergone significant academic and industrial research in the last 15 years. Investigation and solution of low yield problem for phase change memory with lateral fully-confined structure. Hayat, Hasan (et al.) DOI: 10.1016/j.tsf.2016.05.042. Global Phase Change Memory market: Regional Analysis. The most prominent memory in this class is 3D XPoint, developed by Intel and Micron, which is expected to be used in DIMMs for servers. The research report studies the contribution of various regions in the market by understanding their political, technological, social, environmental, and economical status. Because no electrical power is required to maintain either phase of the material, so phase-change memory is non-volatile. 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. 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. Phase change memory can be referred to by a number of names including P-RAM or PRAM, PC-RAM, phase change RAM, and possibly more. Analysts have included data pertaining to every region, its manufacturers, production, and revenue. Phase Change Memory offers the promise of fast RAM speeds, but can be used to store data with low power requirements. Phase-change random access memory: A scalable technology Abstract: Nonvolatile RAM using resistance contrast in phase-change materials [or phase-change RAM (PCRAM)] is a promising technology for future storage-class memory. Phase change memory — an emerging non-volatile technology pioneered by Intel (NASDAQ: INTC), Numonyx, Samsung and others — could turn out to be a low-cost, more reliable, faster, and just plain better alternative to flash memory (see I/O Bottlenecks: Biggest Threat to Data Storage). 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. Institute of Physics (IA) stands out in this research field with a broad collection of experimental methods and theoretical models. Yaling Zhou, Xiaofeng Wang, Yingchun Fu, Xiaodong Wang, Fuhua Yang. Phasenwechselspeicher, Phase Change Memory (PCM), sind nichtflüchtige Speicher, die auf der Änderung des elektrischen Widerstands des Speichermaterials basieren. Regardless of the acronym used, Phase Change Memory represents an innovative type of memory technology with great potential storage application use cases. Phase-Change Memory Device Architecture. However, such a technology can succeed only if it can scale smaller in size, given the increasingly tiny memory cells that are projected for future technology nodes … Villa, Corrado. The phase change memory group of the I. 101--112. Computing: Phase-change memory chips, an emerging storage technology, could soon dethrone flash memory in smartphones, cameras and laptops Die Speichertechnik könnte Flash-Speicher ersetzen, lassen sich damit doch The addition of data in PCM does not require an erase cycle, typical of other types of memory storage. The Global 5 and 10 Largest Players: Market Share by Phase Change Memory Revenue in 2019 Figure 23. Die Grundidee für PCM hat Stanford Ovshinsky bereits 1975 geliefert, inklusive dem passenden Material. Preview. Phase-change random access memory (PRAM) is a new form of nonvolatile memory based on using electrical charges to change areas on a glassy material from crystalline to random. Although the device physics related to the operation of PCM have been widely studied since its … After much development, it is now poised to enter the market as a storage-class memory (SCM), with performance and cost between that of NAND flash and DRAM. Phase Change Memory is also referred to as PCM and PCRAM by different groups. Global Phase Change Memory Production Market Share by Region (2015-2020) Figure 24. Atwood, Gregory. Pages 263-284. Phase change memory employing a Ti diffusion barrier for reducing reset current. Doch die Kontrolle der Phasenänderungen von einem amorphen in einen kristallinen Zustand mit der nötigen Präzision und … Phase Change Memory Market Share by Company Type (Tier 1, Tier 2 and Tier 3): 2015 VS 2019 Figure 21. Built around a two-layer stacked architecture, a 3D XPoint device comes in 128-gigabit densities using 20nm geometries. According to its proponents, PCM technology has the potential to provide inexpensive, high-speed, high-density, high-volume nonvolatile storage on an unprecedented scale. 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].
