Intel cashes in its chips with Micron, bets on post-flash riches

Intel is flogging some its flash foundry capacity in its IMTF joint venture to Micron, its partner in their manufacturing love-in. Chipzilla is selling its stake in two IMTF wafer plants to Micron for $300m cash and a $300m amount held by Micron to pay for future NAND supplies from the plants or to be refunded as cash. Intel and …

Phase change memory arrives

Numonyx has launched two Phase Change Memory (PCM) products under an Omneo brand. Both are 90nm, 128Mbit parts with the P5Q product having a serial peripheral interface and the P8P one using a parallel NOR interface. The P8P is a second-generation product that supports, Numonyx says, one million write cycles. The gen 1 product …

Samsung ships phase-change memory for mobes

Samsung is shipping phase-change memory in a multi-chip package (MCP) as a NOR replacement for mobile phones. Phase-change memory involves storing binary digits as different levels of resistance caused by phase changes in an alloy of germanium, antimony and titanium. The phase changes from amorphous to crystalline and back again …

Flash DOOMED to drive itself off a cliff - boffins

Microsoft and University of California San Diego researchers have said flash has a bleak future because smaller and more densely packed circuits on the chips' silicon will make it too slow and unreliable. Enterprise flash cost/bit will stagnate and the cutting edge that is flash will become a blunted blade. The boffins presented …

No toys to throw from the PRAM

Phase-change memory (PCM or Phase-change RAM - PRAM) seems to be changing its phase, from promising-newcomer-technology to fading-candidate-going-nowhere. PCM is a memory technology involving a change of material state and electrical resistance in a memory cell's chalcogenide layer. The theoretical attractions are that it is non …

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 …

HP demonstrates mega-memory concept

Research work on HP's never-ever-forget Memristor concept is proceeding apace. Memristor technology could provide a new type of computer memory that's much faster than flash memory. HP Labs' engineers in Palo Alto have demonstrated control over how the technology operates, opening the door, they say, to its incorporation into …

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 are …

Hitachi GST SVP takes a punt on STT-RAM

The general manager and VP of Engineering at Hitachi GST has left to join a NAND and DRAM replacement technology company, Grandis. That seems like a risky move. Said GM and VP Mohamad Krounbi is joining Grandis to be its SVP for engineering, taking on responsibility for "all STT-RAM technology and product development at Grandis …

HP pulls memory Missing Link from bottle of beer

More than 35 years ago, when the world assumed that circuits were crafted from three basic building blocks, a man named Leon Chua predicted the existence of a fourth. The capacitor, the resistor, and the inductor, he said, would be joined by something called the memristor. Today, scientists at HP Labs announced that this …

FLASH: The Disruptening

We have had a flash of insight: all the storage array vendors are going to have to face up to all-flash arrays and do something about the technology – buy, partner or build. Denial is not a strategy. Just as disk storage bifurcated into server/PC direct-attach storage (DAS) and shared networked storage (NAS and SAN), so too will …

PCM prototype beats PCIe flash

A first-generation Phase Change Memory device has been built, faster than OCZ's VeloDrive PCIe flash card with random blockI/O but slower with sequential writes. University of California, San Diego (UCSD) student boffins in the Computer Science and Engineering department at the Jacobs School of Engineering built their Moneta …

IBM races bits along a nanowire track

IBM scientists have found out how to move bits precisely at an atomic scale along a nanowire, bringing racetrack memory closer to reality. It's glamming up this project by saying a portable racetrack memory box could store a year's worth of movies. Racetrack memory involves the setting of the magnetisation direction of magnetic …
