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 …

Flashboys: HEELLLP, we're trapped in a process size shrink crunch

The NAND flash industry is facing a process size shrink crunch and no replacement technology is ready. Unless 3D die stacking works, we are facing a solid state storage capacity shortage. The NAND flash foundries are pumping out more and more sub-20nm NAND. Previously they'd mostly produced 2Xnm dies – that is NAND dies with a …

HP's faster-than-flash memristor at least TWO years away

Kavli Foundation Roundtable HP memristor-meister Stan Williams has revealed a product launch delay – saying commercial kit would be available by 2014 at the earliest – and said processor chips would eventually use nanoscale light networking. He was speaking at a Kavli Foundation Roundtable – the Kavli Foundation being one of those US charitable thingies …

The incredible shrinking NAND: I'm MEELLLLTING

Blocks and Files NAND is heading to the graveyard, getting closer and closer with every geometry shrink and every added cell bit. Any replacement NV-RAM technology will require controller software rip-and-replace, which could kill one trick pony flash array startups. NAND flash is non-volatile but expensive to make and both ways of making it …

Resistance is futile? Memristor RAM now cheap as chips

Cheaper memristors could result from an accidental discovery at University College London. The HP-popularised memristor device is a form of ReRAM – resistive RAM – and is fairly expensive to make. Metal oxide-based ReRAM technology promises to combine minimum memory speed with NAND non-volatility and be able to provide higher …

Rambus drops $35m for Unity Semiconductor

Rambus is spending $35m (£22.13m) in cash to buy Unity Semiconductor and get into the post-NAND memory business. Unity is involved with CMOX resistive RAM technology, said to combine DRAM speed and NAND non-volatility. It hopes to produce a 1 terabit chip by 2014. Unity's people will be joining Rambus, putting an end to any …

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 …

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 …

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 …

Memristors can maybe learn like synapses

Memristors can potentially learn like synapses and be used to build human brain-like computers according to Wei Lu, a University of Michigan scientist. He thinks that two CMOS circuits connected by a memristor is analogous to two neurons in the brain connected by a synapse. It is thought that synaptic connections strengthen as …

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 …
