<< endobj /Filter/DCTDecode Well, it’s not. Interesting guy / family. While we were initially told at the XPoint announcement event Q&A that the technology was not phase change based, there is overwhelming evidence to the contrary, and it is likely that Intel did not want to let the cat out of the bag too early. 8 0 obj There have been a few very vocal folks out there chanting 'not good enough', without the basic understanding that the first publicly available iteration of a new technology never represents its ultimate performance capabilities. /BitsPerComponent 8 Allyn– Thank you for a greatAllyn– Thank you for a great article. 4 0 obj P8P parallel phase change memory (PCM) is nonvolatile memory that stores informa-tion through a reversible structural phase ch ange in a chalcogenide material. X�Eȱ �U~��R,�qw���(uy�d�b#����9��� Phase Change Memory offers a key advantage of NVRAM: unlike Dynamic Random-Access Memory(DRAM) which is another common type of system memory, NVRAM allows information to be retained when the system is powered off. Micron has spent a bunch of money on phase change including the … /Domain[0 1] … /Domain[0 1] over, with royalties to his estate and/or favorite charity. An overvoltage would/could divert excess voltage away from sensitive circuitry. Micron says the standard accepted endurance for DRAM is “>1E15 cycles”. If the views of Greg Atwood of Micron Technology on phase-change memory (PCM) scalability are a measure of the quality of his paper, The evolution of phase-change memory, then its overall value is suspect. ‘Blank’ media was crystalline, and pits were written by heating spots by pulsing the write laser. Numonyx to Present Phase Change Memory Research Results at Leading Technology Industry Conference GENEVA – December 1, 2009 – Numonyx B.V. researchers will present their latest findings on phase change memory (PCM) next week at the 2009 International Electron Devices Meeting (IEDM), the world's main forum for reporting breakthroughs in technology, physics and the modeling of … Some die-level performance characteristics of various memory types. Alloys of varying mixtures of the semimetals have been experimented with for decades. Finally, the Phase Change Memory Market report is the believable source for gaining Market research that will exponentially accelerate your business. Micron used to sell the highest density PCM chip made and it has disappeared from its offerings. Learn, imagine, innovate, solve, and gain insight on the technology trends of today and tomorrow from thought leaders around the world. We can also see where the ~1000x speed and ~1000x endurance comparisons with XPoint to NAND Flash came from. Attributes of PCM materials. �� 1 �� We will be in touch. /Length 172987 A 3D XPoint die, submitted for your viewing pleasure (click for larger version). The “gets smaller, becomes more reliable” is quite the interesting attribute, and I liked the comparison to DVDRAM/RW. Nice to see Stanford Ovshinsky get more vindication. Yeah. • January 1955: Kolomiets and Gorunova revealed semiconducting properties of chalcogenide glasses. DVD-RAM actually used GST compounds but relied on its changing optical properties as opposed to electrical conductivity. w/ a few Photoshopped red streaks Allyn dives in the idea of 3D XPoint being phase-change memory and details how it functions. Change the world. Both Intel and Micron are producing solid-state drives (SSDs) based on 3D XPoint chips, chips that are believed to be an embodiment of chalcogenide phase-change memory technology. << Learn how your comment data is processed. Comment So, is XPoint memory phase-change memory … or not? Push the little pixels and make them dance. endobj First PCM Solution in the World in Volume Production. The common phase change alloy is a 2:2:5 stoichiometric ratio of Germanium, Antimony, and Tellurium. The research report, titled [Phase Change Memory Market Research Report 2020-2026], presents an unbiased approach at understanding the market trends and dynamics.Analysts have studied the historical data pertaining to the market and compared it to the current market trends to paint an object picture of the market’s trajectory.
