of a collaboration with Intel’s Gordon Moore. 1 chip maker early leadership in a nonvolatile-memory technology touted as a successor to flash and DRAM. The structure of a typical non-volatile memory cell includes a storage element combined with a selector element. Some are The connection allows for the selection of a single storage element inside of a large array of cells -- a billion or more. A cinematographic study in 1970 established that the phase-change-memory mechanism in chalcogenide glass involves electric-field-induced crystall… Senior Reporter Lucas Mearian covers financial services IT (including blockchain), healthcare IT and enterprise mobile issues (including mobility management, security, hardware and apps). In 1969, Charles Sie published a dissertation, at Iowa State University that both described and demonstrated the feasibility of a phase-change-memory device by integrating chalcogenide film with a diodearray. On Dec. 9, the two companies plan to present a paper on their discovery at the 2009 International Electron Devices Meeting, titled "A Stackable Cross Point Phase Change Memory.". Sure, its exciting to see flash memory drop in price and increase in capacity, but flash isn't the end-all-be-all. Additionally, since the silicon substrate that isn't being used as a selector, as it is in today's PCM product, can now be used for building the support circuitry used that's required to decode, read and write to the cells. Subscribe to access expert insight on business technology - in an ad-free environment. "This switch demonstrates a diode-like behavior. Mass production … Phase-change memory differs from other solid-state memory technologies such as flash and random-access memory because it doesn't use electrons to store data. Copyright © 2009 IDG Communications, Inc. It has a low current in the off state and a high current in the on state," Atwood said. When phase-change becomes standard, it would be all that was necessary rather than a DRAM or SRAM module that reads and writes data quickly while the flash memory is just there to store data when the power is off. Even if flash were to be obsolete tomorrow it'd still be remembered as having been a massive success. The state change has an associated resistance change, and reading the resistance level reveals the binary value of the resistance level. Now, Intel has discovered that there are two more distinct states between amorphous and crystalline that can be used to store information, doubling the capacity of the memory. Intel, STMicroelectronics Deliver Industry's First Phase Change Memory Prototypes . Phase-change memory is made up of a glass-like material called chalcogenide that can be can be switched between a crystalline and random state using very low-voltage electricity. The breakthrough in stacking PCMS came with the use of a thin film selector substance that is in the same class of materials as chalcogenide and is built above the silicon substrate. The function of the storage element is nonvolatile storage of data and the purpose of the selector element is to connect storage elements into a cross-point array of cells. Atwood said that because the stacking breakthrough builds on top of PCM, a technology already in production, "it's a leading candidate amongst the various stackable memory concepts, most of which have no basis in a proven technology.". Intel Corp.'s surprising disclosure last week that it plans to have 90-nanometer, 128-Mbit phase-change memory in volume production by year's end seemingly gives the world's No. 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. "So the combination of these two advantages results in a much smaller die size that's a lower potential cost structure for the memory," Atwood said. Instead, it relies on the material's own arrangement of atoms, known as its physical state. Phase-change memory, to recap, is a chalcogenide (glass-like) material which changes its internal state from amorphous to crystalline and back again when the appropriate amount of electricity is applied to it. Phase change memory uses a special alloys, including Germanium Antimony Tellurium (GST), which have innovative characteristics that enable the non-volatile storage. flash memory drop in price and increase in capacity. Intel, after recently reviewing its memory technology roadmap, speculated that phase change memory (PCM) will possibly be available by the end of the year. Previously, phase-change memory was designed to take advantage of only two states: one in which atoms are loosely organized (amorphous), and another where they are rigidly structured (crystalline). "And, it's of particular interest given the challenges the existing non-volatile memory technologies are facing over the next decade as well as the continued expansion of [PCM] usage.". SANTA CLARA, Calif and GENEVA, Feb. 6, 2008 – Intel Corporation and STMicroelectronics reached a key industry milestone today as they began shipping prototype samples of a future product using a new, innovative memory technology called Phase Change Memory (PCM). Intel Xpoint Memory is a PCM (Phase Change Memory) with a double storage-selector stacked memory cell between metal 4 and metal 5. Intel sells 3D XPoint devices for solid-state storage drives (SSDs) and other products. Intel 3D XPoint PCM (Phase Change Memory) viene a revolucionar el mundo y por primera vez sin el uso de transistores. ... supported in part by Intel Corporation, the Semiconductor Research Corporation under. Nearly 30 years later, ECD formed a new subsid-iary, Ovonyx, a joint venture between ECD and Tyler Lowery, the former CTO, COO and Vice-Chairman of Micron Technology. This story, "Intel, Numonyx create breakthrough in phase-change memory" was originally published by Phase Change Memory.pdf. Phase change memory is a memory device which typically uses a chalcogenide material for the memory elements. "It has features of a low-latency memory and high bandwidth so we can combine many of the good attributes ... of NAND flash, DRAM and NOR flash," Fazio said. Unlike NAND flash memory, which requires a entire block of memory cells to be rewritten each time new data is stored on a device like a SSD drive, PCM allows for single bits to be changed, greatly increasing the efficiency and performance of a device. PCMS is comprised of one PCM element layered with a newly used Ovonic Threshold Switch (OTS) in a true cross point array. Intel and Numonyx today announced a breakthrough in the development of a multi-layer phase-change memory product that has the potential to replace NOR and NAND flash memory as well as DRAM. Phase change memory (PCM) looks like it might be the most viable alternative to solid-state. But there is some circumstantial evidence for it being phase-change memory technology implemented in … Phase change memory can quickly shift between the two states, plus research from Intel and Micron have demonstrated the feasibility of intermediate states, which … 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. Phase-Change Memory Advantages Write Performance / Data Retention With single-bit alterability, PCM technology delivers significantly better write and comparable read performance than Flash-based memories that require at least a byte- or sector-erase cycle before reprogramming. These modules are based on 3D Xpoint memory, a form of phase-change non-volatile memory. Intel and Numonyx held a press conference earlier today to discuss a phase change memory (PCM) breakthrough many years in the making. the phase change memory (PCM), it is only in the past 10–15 years that advances in materials and device tech- ... supported in part by Intel Corporation, the Semiconductor Research Corporation under Contract 2009-VJ-1996, the National Science Foundation under Grant CBET-0853350, LONDON — Intel Corp. (Santa Clara, Calif.) is preparing to sample a 90-nm 128-Mbit phase change memory to customers in the first half of 2007. On the standalone front, Intel for some time has been shipping a device called 3D XPoint, a next-generation memory based on phase-change. Intel and Numonyx today announced a breakthrough in the development of a multi-layer phase-change memory product that has the potential to replace NOR and NAND flash memory … Other non-volatile memories in development include graphite memory , and race track memory . Mouser is now stocking Optane memory modules from Intel with capacities of up to 512GBytes. In operation, the phase change memory stores information on the memory element by changing the phase of the memory element between amorphous and crystalline phases. The September 28th, 1970 issue of Electronics2 featured the world’s first Phase Change Memory, a 256 bit semiconductor device. Phase change memory is based on a technique known as the memresitor that was initially developed by Hewlett Packard. This change is very rapid; in the ten nanoseconds range. He was the lead author for the groundbreaking 1970 PCM article in Electronics Magazine, co-authored by Intel’s Gordon Moore (of Moore’s Law fame) introducing the world’s first PCM, a 256-bit device. They cal it PCMS (phase change memory and switch). Greg Atwood, a senior technology fellow at Numonyx, said the breakthrough in stackable PCM, which is being called PCM-stackable (PCMS), has the potential to create products that can replace DRAM, NOR and NAND flash memory because it will have better bandwidth, greater density and a cost per gigabyte of capacity comparable with today's solid state disk (SSD) drive products. Intel and Micron chose not to reveal the materials they are using or the switching mechanism at play in their 3D XPoint non-volatile memory launched earlier this week. Phase-change memory (PCM) is an emerging non-volatile memory technology that has recently been commercialized as storage-class memory in a computer system. This memory operates by changing the conductivity of a cell from low to high (the phase change). PCM, however, currently has the ability to scale to 5 nanometers in size, and the potential of even greater densities, Fazio said. GST-based materials are used for the storage, while As (arsenic) doped chalcogenide materials (Se-Ge-Si) are used for the selector in which As might be used to suppress crystallization. What!? Phase-change memory (PCM) exploits properties of chalcogenide alloy, the internal state of which varies between crystalline and amorphous phases with different levels of electrical resistance. A memory element is the unit that actually stores information. 1 chip maker early leadership in a nonvolatile-memory technology touted as a successor to flash and DRAM. Micron and Intel co-developed 3D XPoint, a type of phase change memory in a crosspoint array, to fill the performance gap between more expensive DRAM and cheaper NAND flash. Al Fazio, an Intel fellow and director of memory technology development, said it's not unusual for a new memory type to take as many as 10 years to develop. Esta avanzada tecnología utiliza las propiedades de los materiales en la celda de memoria para almacenar el dato y puede acceder a un bit de la misma o a una palabra (varios bits) mediante cables y selectores colocados en su estructura 3D. While getting a laptop with an SSD inside is still ridiculously expensive, it won't be that way for. Intel Corp.'s surprising disclosure last week that it plans to have 90-nanometer, 128-Mbit phase-change memory in volume production by year's end seemingly gives the world's No. Flash memory was invented in 1984 (by Toshiba) and has been enormously successful. In the 1960s, Stanford R. Ovshinsky of Energy Conversion Devices first explored the properties of chalcogenide glasses as a potential memory technology. And Intel just figured out how to double the capacity of phase-change memory, shortening flash's lifespan before it's even really taken off. Atwood added that Intel and Numonyx have no current time line for bringing PCMS products to market. Webb gave a series of presentations at the recent virtual Flash Memory Summit. Intel Corp. and Numonyx B.V. announced a breakthrough in the development of phase-change memory today that has the potential to allow developers to stack multiple layers of chips atop each other, thereby greatly increasing the density of the nonvolatile memory medium. Part two will cover nanotube RAM, ferroelectric RAM, and phase-change memory. How 3D XPoint Phase-Change Memory Works I’ve seen a bit of flawed logic floating around related to discussions about 3D XPoint technology. Future roadmaps scale NAND flash to 20 nanometers, but physical limitations present a barrier to creating anything more dense than that. "Combining the OTS with the thin film storage material, a similar material used in phase-change memories today, enables a cell that can be stacked multiple layers high." It's as fast as the DRAM and SRAM that's used in conjunction with flash memory now. Computerworld.

Calling the discovery a "milestone" in phase-change memory (PCM) development, the researchers said they have so far only been able to build a single-layer, 64Mbit chip with the potential to be stacked with other 64Mbit chips. Memory cards, mobile phone SIM cards, MP3 players, etc, all use flash. Ron’s career has centered around phase-change memory. 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. In fact, we already know what it'll be replaced by before it's even become the de facto standard: phase-change memory. Mouser sells Intel's phase change memory on DDR modules. The companies are calling the thin film selector an Ovonic Threshold Switch (OTS), which acts like a resister between the stacked layers of PCM chips. The alloy can be altered with heat to have two different states or "phases" (crystalline and amor… Don't worry, though. Micron bought out Intel's interest in IM Flash Technologies in Lehi, Utah, and the vendors ended their joint development work. Intel and Numonyx researchers are now able to demonstrate a vertically integrated memory cell – called PCMS (phase change memory and switch). Intel and Numonyx have announced a new memory technology that "paves the way for scalable, higher density phase change memory (PCM) products". Intel and STMicroelectronics have developed a new type of phase-change memory chip that doubles the memory density over previous versions, giving a … Content available from H.-S. Philip Wong: 0c960520fc53fdc107000000.pdf. PCM is also being explored for non-von Neumann computing such as in-memory computing and neuromorphic computing. August 11, 2020 // By Peter Clarke. Analysis A team of scientists from China have asserted that 3D XPoint is essentially phase-change memory, which manufacturers Intel and Micron have not publicly admitted. Just because flash-based SSDs are only just taking off doesn't mean that flash memory is. Copyright © 2021 IDG Communications, Inc. Phase-change is superior to flash as it's much faster. Senior Reporter, And Intel just figured out how to double the capacity of phase-change memory, shortening flash's lifespan before it's even really taken off. The two companies have been working on development of PCM products since 2000, and a stackable PCM product since 2002. This can be achieved by applying a voltage to modify the cell state. They have created a 64Mb chip that enables to stack multiple layers of PCM arrays in a single die. [Technology Review via Slashdot], "...shortening flash's lifespan before it's even really taken off". Like many new memory types, phase-change memory comes in two forms—standalone and embedded. Current NAND flash memory lithography technology resides at the 32-nanometer level. Phase-change memory won't be hitting consumer devices for another few years, so your expensive flash-equipped devices won't be going obsolete… yet. Computerworld |.
