IBM's Phase Change Memory computer can tell you if it's raining

IBM boffins have unveiled new work in-memory computing: doing processing inside Phase Change Memory with no external CPU. Traditional computing requires a memory to hold data and an external processor to which the data is transferred, processed and then written back to memory. This is the Von Neumann architecture and, can be …

Great, IBM has had a PCM breakthrough. Who exactly is going to manufacture?

Analysis IBM has demonstrated a 3-bit Phase-Change Memory chip with IBM Zurich researcher Dr. Haris Pozidis talking about it in a YouTube video and not mentioning 3D XPoint once. The idea is to counter the relatively high cost of PCM chips by giving them 3 bits per cell, TLC or triple-level cells, instead of just one - clever. This …

Storage with the speed of memory? XPoint, XPoint, that's our plan

Analysis Since the virtual dawn of computing, storage – where data puts its feet up when it's at home – has been massively slower than memory, where data puts on its trainers and goes for a quick run. That massive access speed gap has been getting narrower and narrower with each storage technology advance: paper tape, magnetic tape, …

Data boffins see the light with extravagantly bit-blessed optical PCM

As if PCM (phase change memory) wasn’t esoteric enough, we now have optical PCM, thanks to sterling boffinry efforts at Oxford and other universities. Material scientists at Oxford University, Karlsruhe, Munster and Exeter have produced the world’s first all-photonic, non-volatile memory chip. It uses Ge2Sb2Te5 (GST), a …

Drifting phases and noise in phase-change memory

Phase change memory cells can, well, change, over time. Once set in their crystalline or amorphous phases the material can drift towards the other state rendering the cell's resistance level less clear and weakening its ability to story a binary one or zero. PCM (Phase-Change Memory) is one of the candidate persistent storage …

HGST sets hearts aflutter with second sexy PCM demo

HGST is being a sexy beast and strutting its Phase Change Memory stuff once again, at the Flash Memory Summit. Sex sells in the flash biz and HGST thinks it has a hot little number – again – with its Phase Change Memory technology. A year on from its 3 million IOPS/1.5 microsecs latency demo of a PCIe-connected PCM SSD, it is …

A day may come when flash memory is USELESS. But today is not that day

The era of flash memory is anticipated to run out of road in the 2020s and newer technologies involving resistance and electron spin are poised to take over, delivering higher capacities, greater speed and DRAM-style addressability. Some people ask if one of these new technologies could actually unify dynamic memory (RAM) and …

Aggressive HGST hurls flashy humdingers at online archiving

Comment Holy Moly, HGST is getting ambitious. It's building an active archive platform product in competition with some of its OEMs and its aiming to rewrite server clustering with a flash fabric - oh and develop helium-filled disk drives - and shingled drives with its own slant - and thinking of Phase Change Memory chips with DIMM …

HGST brings PCM to flash show, STUNS world+dog with 3 MILLION IOPS

In a terrific demo of the wrong technology for the Flash Memory Summit, HGST is showing a PCIe-connected Phase Change Memory device running at three million IOPS with a 1.5 microsecs read latency. Phase Change Memory (PCM) stores binary digits as differing resistance levels by changing the state, or phase, of the chalcogenide …

Storage memory has a DIMM future... and that's a GOOD thing

Blocks and Files The SMART flash DIMM announcement has opened up a major server memory redesign period. The idea of packing NAND chips tightly together and accessing them in the same address space as main memory is highly attractive to server manufacturers looking for an edge in running applications faster – faster than PCIe flash for example …

Look out, Flash! Phase-change RAM IS HERE ... in Nokia mobiles

Micron is shipping phase-change memory to Nokia for use in its Asha smartphones. Phase-change memory (PCM) stores each binary bit using the electrical resistance of a chalcogenide chemical: when the material is an amorphous blob, its resistance is high and it represents a 0; in its poly-crystalline state, its resistance is low …

HP boffin: Honey! I shrank the PC. To nanometre size, dammit

HP boffins have packed layers of RAM, caches and storage into a combined block of memristors and processor cores to create highly scalable "nanostore" systems. It's hoped these little monsters will chew through mountains of data with terrific energy efficiency. A memristor increases or decreases its electrical resistance …

EMC flash man: PCM will save us from the Incredible Shrinking NAND

EMC's flash exec expects Phase Change Memory - one of the possible non-volatile successors to flash - to appear in storage architectures from next year. Phase Change Memory exploits the differing resistance levels in chalcogenide materials as they change from an amorphous to a crystalline state and back again, background here …

Micron mass-produces Phase Change Memory

Memory maker Micron has become the first firm to put Phase Change Memory (PCM) - one of the possible non-volatile successors to Flash - into mass production. Caveat: we're talking the technology's use for mobile devices only. Micron is pitching its initial offering at mobile devices, combining 1Gb of 45nm PCM and 512Mb of low- …

Micron's glass memory monster chews up slowcoach flash

Micron has demonstrated Phase-Change Memory (PCM), enabling an app to run around 50 times faster than it would on NOR memory. PCM is a post-NAND and post-NOR contender in the non-volatile memory arena; it's said to combine the speed and simple data access of DRAM and the non-volatility of NAND and NOR flash memory. It stores …

Fujitsu CTO: Flash is just a stopgap

Flash is a necessary waystation as we travel to a single in-memory storage architecture. That's the view from a Fujitsu chief technology officer's office. Dr Joseph Reger, CTO at Fujitsu Technology Solutions, is that office-holder, and – according to him – flash is beset with problems that will become unsolvable. He says we …

IBM boffins claim phase change memory breakthrough

Fast and reliable non-volatile memory of some sort that will replace flash memory is the dream of more than a few semiconductor researchers and chip makers. And boffins at IBM Research in Zurich, Switzerland, think they have come up with a new encoding technique that will allow for multi-level cell (MLC) phase change memory to …
