Intel and Numonyx pave the way for scalable, higher density phase change memory

by Darren Murph posted Oct 30th 2009 at 1:51AM

Both Intel and Numonyx have been talking up phase change memory for years now, but for some reason, we're slightly more inclined to believe that the latest breakthrough is actually one that'll matter to consumers. In a joint release, the two have announced a new non-volatile memory technology that supposedly "paves the way for scalable, higher density phase change memory products." Put as simply as possible, researchers have been testing a 64Mb chip that "enables the ability to stack, or place, multiple layers of PCM arrays within a single die," and the two are calling the discovery PCMS (phase change memory and switch). We know, you're drowning in technobabble here, but if these two can really apply Moore's Law to density scaling, you'll be thanking 'em as you pick up your $50 6TB hard drive in 2014.

Intel announces 22nm chips for 2011

by Nilay Patel posted Sep 22nd 2009 at 12:14PM

Paul Otellini just held up a 22nm wafer at his Intel Developer Forum keynote, saying that chips with the technology would be out in the second half of 2011. Take a good look, kids: that's 2.9 billion transistors right there.

Rambus and Kingston build a threaded module prototype, claim 50 percent better memory throughput

by Vladislav Savov posted Sep 21st 2009 at 7:48AM

How do you thread memory tasks and are women naturally better at it than men? Such were the questions that roamed our limitless minds as we sought to understand what exactly Rambus and Kingston had achieved. Based on standard DDR3 chips, the new threading tech essentially creates multiple independent channels per memory module, allowing multicore processors to utilize the available RAM more efficiently. That results, says Rambus, in systems that offer 50 percent higher throughput that the standard stuff and suckle 20 percent less power due to the compartmentalization of each module. Neat. More details are promised at the Intel Developer Conference, which kicks off tomorrow in San Fran.

Samsung debuts first 32GB DDR3 memory module

by Donald Melanson posted Jun 18th 2009 at 3:38PM

Samsung has been making promises about a 32GB DDR3 memory module since it rolled out its first 50nm 4Gb DDR3 memory chip way back in January, but it looks like it's now finally delivered. While it won't be headed for regular desktops or laptops just yet, the company does have a new 1.35 volt 32GB module for servers which, in addition to packing that record-breaking capacity, also boasts a 20% better throughput compared to previous 1.5 volt modules and, of course, a lower power consumption to boot. As some math not performed by us will reveal, the module itself is made up of 72 of those 4Gb memory chips, which are lined up in rows of nine quad-die packaged 16Gb DDR3s mounted on each side of the circuit board. No word on pricing just yet, nor is there any word about Samsung's promised desktop and laptop memory, which are apparently still in the works -- in the form of 8GB DIMMs, at least.

Dell's Mini 10v gets unboxed, cracked wide open, fitted with OS X

by Darren Murph posted May 31st 2009 at 2:08AM

Not that Dell's other Mini machines aren't perfect candidates for creating your own hackintosh, but it's stellar to know that the outfit's newest member is as well. After going on sale earlier this month, the Mini 10v has been procured, unboxed and dissected, all in the name of unabashed discovery. Interestingly, it seems as if the RAM slot requires that the keyboard and motherboard be lifted for access, but for even the mildly seasoned computer user, that's absolutely nothing they can't handle. If you're into hardcore, uncensored splayings of newfangled netbooks, the read link is where you need to be, holmes.

Corsair DDR3 memory clocked at 2533MHz, women swoon 'round the world

by Joseph L. Flatley posted May 21st 2009 at 12:23PM

Corsair -- the swashbucklin' favorite of privateers in need of RAM and SSDs -- has just announced that its Dominator GT DDR3 memory has been overclocked at a pretty astonishing 2533MHz. As you'd expect from a company made of braggarts and rogues, its claiming the world record for itself -- unless, of course, one of you other memory manufacturers feels like taking this bad boy on. Kingston, we're looking at you. Hit that read link for all the salacious details.

Samsung's PRAM chips hit mass production in June

by Ross Miller posted May 5th 2009 at 9:39PM

Mark your calendars, memory enthusiasts, for the date you've all been waiting for. Samsung's phase change RAM will go into mass production starting in June. The PRAM chips -- not to be confused with parameter RAM, often what you curse / reset if you've got a Mac on the fritz -- can rewrite data without having to erase what's already on there first. The company's still boasting it's 30x faster and has 10x the lifespan of traditional flash memory. You want to know what gadgets and gizmos will first use these chips? Us too, but we're all gonna have to wait because Sammy's not talking yet.

OE-A shows off nonvolatile RAM, RFID tag formed by printing

by Darren Murph posted Feb 27th 2009 at 3:30AM

While it's far from being noteworthy to the mainstream public, printable electronics hold a lot of promise. Over at Printable Electronics 2009 in Tokyo, the Organic Electronics Association (OE-A) demonstrated some of the most extreme, useful printings that we've seen to date. By utilizing an eclectic array of printing methods, the agency was able to produce nonvolatile RAM with a capacity of 1,024 bits (for use in ID and game cards) along with a printed RFID tag that could be launched today in logistics operations. We doubt very seriously that mere consumers will soon have access to printers of this nature, but if we can now print memory and wireless identification tags, one must wonder: what on Earth is next?

DDR3 shootout pits OCZ, Kingston and Corsair against one another

by Darren Murph posted Feb 25th 2009 at 3:13PM

DDR3 modules aren't exactly new or anything, but given just how low the prices of big time kits have become, we figured it prudent to pass along one of the most thorough shootouts on the subject that we've seen. HotHardware grabbed a few DIMMs from the labs of OCZ Technology, Corsair and Kingston, threw 'em all in a Core i7 rig (not simultaneously, silly!) and benchmarked the lot until they literally fell asleep at the keys. The results? We'd love to tell you which sticks came out atop the pile, but that would just be spoiling the fun for you, now wouldn't it? Give the read link a look if you're ready for the action.

Toshiba makes progress on FeRAM, still no tangible product in sight

by Darren Murph posted Feb 9th 2009 at 2:58PM

Phew. For a ~~moment~~ year or so there we reckoned that amazing FeRAM discovery had been pushed aside and forgotten entirely. Thankfully, Toshiba has picked up the ball and refined the original chainFeRAM architecture by creating a new architecture that prevents cell signal degradation -- which, as you may or may not know, is the usual tradeoff from chip scaling. In essence, this has allowed the company to design the world's highest bandwidth, highest density (128-megabit) non-volatile RAM. Unfortunately, this amazing device -- which should realize read / write speeds of 1.6 gigabytes a second and combine the fast operating characteristics of DRAM with flash memory's ability to retain data while powered off -- is still in prototype form, which probably means we're months (if not years) away from actually seeing a tangible end product hit store shelves.

Rambus introduces 4.3Gbps mobile memory

by Nilay Patel posted Feb 2nd 2009 at 1:32PM

It's not all just lawsuits and overinflated posturing for Rambus -- the prickly memory firm will later today demo what its calling the Mobile Memory Initiative, a 4.3Gbps phone-oriented variant of the XDR RAM used in the PS3 that requires just 100mV of power. That means companies can either build super-powerful phones that take advantage of a complete MMI system's estimated 17GBps throughput, or build cheaper devices that offer performance equivalent to today's memory with fewer MMI parts. Rambus won't say who it's working with to bring out MMI, but we're going to have to wait a bit before we all score cheap HD videophones -- the first products aren't scheduled to hit until early 2010.

Samsung seems pretty proud of world's highest density DRAM chip

by Darren Murph posted Jan 29th 2009 at 12:21PM

Those of you who actually keep track of which outfits are on top of others in terms of density (yeah, all 8.4 of you) have a new winner to document, as Samsung has just announced the development of the planet's highest density DRAM chip. By utilizing 50 nanometer technology, Sammy has concocted a four gigabit DDR3 DRAM chip, and if it has its druthers, the low-power device will be used in data centers and servers the world over. The module can be produced in 16GB registered dual in-line memory modules (RDIMM) for servers, as well as 8GB unbuffered DIMM (UDIMM) for workstations and desktop PCs, and 8GB small outline DIMM (SODIMM) for laptops. If dual-die package technology is tapped into, the new device can scale as high as 32GB, though Samsung is careful not to mention just how much you'll have to pay for this stuff.

Corsair's Peltier memory cooler gets demonstrated

by Darren Murph posted Jan 11th 2009 at 3:42AM

Corsair's Dominator memory can apparently get quite hot, particularly if the overclocking bug catches you right. If a product shown off at CES hits the commercial market, however, everything is sure to stay cool. The Peltier cooling device is expected to play nice with second-gen Dominator modules, and when attached to existing heatsinks it can be used to cool a larger heat block in pretty much any water cooling setup. We know, you're probably scratching your head, but hop on past the break for a quick video demonstration.

[Thanks, Ryan]

Korean scientists create transparent memory chip... or so they tell us

by Ross Miller posted Dec 17th 2008 at 2:35AM

Researchers at the Korea Advanced Institute of Science and Technology claim to have created a see-through non-volatile memory chip based on resistive random-access memory (RRAM) technology. Made with transparent oxide film and electrodes on clear glass or plastic circuit boards, the group believes commercial production could begin in 3 to 4 years and could be cheaply manufactured (current backers of RRAM include Fujitsu, Sharp, Samsung and others). They're hopeful the new technology will pave the way for transparent devices such as monitors and televisions. No images of the transparent chip have been published -- but they're not much to look at, anyway.

New MacBooks said to have issues with maxed out RAM, faulty NVIDIA GPU

by Donald Melanson posted Dec 9th 2008 at 2:54PM

While most of the complaints about the new MacBooks and MacBook Pros have focused on things like the screen or the absence of a certain much-loved port, it appears that another problem has been bugging some folks that went ahead and maxed out the RAM on their shiny new laptop. Apparently, loading 4GB of RAM (either from Apple or a third party) has caused at least a few MacBooks and MacBook Pros to freeze up randomly which, for the time being at least, can only be remedied by dialing things back to 2GB or 3GB of RAM (something tested by jkOnTheRun). While Apple isn't saying anything publicly about this just yet, one member of the Apple support forum claims to have heard from an Apple engineer who says that Apple is, in fact, aware of the problem and that a software update is on the way to fix it, possibly within a few days.

In related MacBook news, The Inquirer is now reporting that the new MacBook Pro's NVIDIA 9600M GPU suffers from the same so-called "bad bump" problem that has plagued previous generation MacBook Pros (and provided plenty of fodder for The Inq) which can, in some cases, lead to blank screens and other video errors. It's not clear, however, if the problem affects all MacBook Pros or just a bad batch, although there does appear to be a somewhat sizable number of complaints cropping up.
