Fast silicon is hitting a wall in game PCs, according to Alienware, which is looking for ways to boost game PC performance.

Parent company Dell vowed on Tuesday to pour more resources into the game PC unit and invest in "product development, design, and engineering."

Alienware's Marc Diana believes optimizing systems for the 64-bit world would allow game PCs to make big strides in performance. In effect, today's 32-bit environments are putting a crimp on PC-based gaming.

"So many people are caught up in this hardware race. Dual-core, quad-core this and that," said Diana, … Read more

With yesterday's launch of the WiiWare service, it's now easier than ever to fill up your Wii to the point of full capacity. It doesn't take much to fill up those 2,163 blocks (about 512MB)--between additional channels, the virtual console, and now WiiWare, you're going to need to be doing some serious maneuvering if you want to experience everything the Wii has to offer. So why hasn't Nintendo come up with a solution that can allow owners to expand the storage capacity?

While the SD card slot is nice, for many Wii owners it has become strictly a way to back up game saves. You can't directly access it in-game nor can you play virtual console or WiiWare games directly off of it. Why not enable this? Surely this can be accomplished with a Wii system update. And by limiting the memory capacity, Nintendo is essentially preventing customers from buying more virtual console and WiiWare titles.

Rumors of a storage add-on have come and gone, with nothing ever manifesting. If Nintendo plans on adding a new WiiWare title every Monday--in addition to the new virtual console titles they release each week as well--something needs to be done to address this growing concern.

While we'd all like for the SD card slot to allow in-game read and writing capabilities, or for the ability to connect a USB flash-drive, we're guessing it will probably be a Nintendo-branded… Read more

It was a search for the essence of things that lead to the memristor, says UC Berkeley professor Leon Chua.

This week, HP Labs announced it had made a memristor, or memory resistor, a fundamental circuit element first theorized by Chua decades ago. If they become commercially practical to make, memristors could lead to very dense, energy-efficient memory chips that don't cost much because they don't need much silicon. A memristor has a variable resistance; as a result, memristors can "remember" how much charge was applied to it. (See here for more on HP's memristor.) … Read more

It's the tale of the lost circuit.

Thirty-seven years ago, Leon Chua, a professor at the University of California at Berkeley, mathematically theorized that scientific symmetry demands that there should be a fourth fundamental circuit element. Engineers were already familiar with resistors (which resist the flow of electricity), capacitors (which store electricity), and inductors (which resist changes to the flow of electrical current), which can be combined to build more complex devices. The fourth circuit, which Chua called a "memristor" for memory resistor, would register how much current had passed.

"He looked at fundamental circuit equations … Read more

Toshiba is planning to ship 512GB solid state drives by 2009 when it expects these storage devices to claim one-fourth of the market, according to Japan-based reports.

Toshiba is currently getting set to ship 128GB solid state drives (SSDs), which it plans to offer by June in its Dynabook SS RX1 and Portege notebooks. SSDs are based on NAND flash memory, a market that Samsung and Intel also compete in.

The market for SSDs used in notebook PCs will surge on average 313 percent per year through 2011, according to a report from Nikkei Business Publications. The report referred to … Read more

Don't make computers seek out data. Make the data move to where it can be used.

That, roughly, is one way to describe the racetrack memory concept, which IBM argues could one day lead to memory that could hold 100 times more data than flash memory does today and cost 100 times less. So that 2GB card you bought for $20 this week would hold 200GB, or more than a lot of notebook hard drives, and cost 20 cents.

In racetrack memory, information is stored in the domain walls, or boundaries, between magnetic regions on a wire. The domain … Read more

Cell phones and smartphones increasingly rely on microSD media for added storage. A 2GB card would let you carry a few ripped movies, about 500 MP3s, loads of photos, countless documents, and so on. SuperMediaStore.com has a PQI 2GB microSD card on sale for just $8.99. No rebates, free shipping, beat that.

The card comes with a fairly important extra: an SD adapter so you can use it with the vast majority of media-card readers (few of which have microSD slots). It even comes in a retail package, so it qualifies for PQI's lifetime warranty. Pretty sweet … Read more

Apple has cut its 2008 flash memory orders by $200 million, according to iSuppli, setting up a down year for flash vendors.

In February, iSuppli reported that Apple was slashing its orders of flash memory amid a weakening economy, but iSuppli wasn't sure exactly how far the cuts would go. After crunching the numbers, iSuppli now expects Apple to spend $1.4 billion on flash this year for iPods and iPhones, up 12 percent from $1.2 billion last year. But the analyst firm, and the flash memory industry, had been expecting much more purchasing out of Apple, at … Read more

Micron Technology announced that it is sampling 4 gigabyte (GB) memory modules based on high-speed DDR3 technology and said the memory has been validated by Intel to run on its upcoming Centrino 2 mobile processor.

DDR3 SDRAM or double-data-rate three synchronous dynamic random access memory is expected to be faster than DDR2 SDRAM--now used widely in systems--though this will depend on the speed rating of the DDR3 memory and on what type of DDR2 memory it is tested against.

Micron's DDR3 modules support data rates of up to 1333 megabits per second, enabling better system and graphics performance. DDR3 … Read more
