IBM and partners show off 28nm chip

IBM and partners show off 28nm chip

IBM and several of their partners such as Infineon, Samsung, STMicroelectronics and Chartered Semiconductor are working together to create a 28-nm chip that requires less power and features a high-k metal gate bulk complementary metal oxide, so says an announcement released yesterday.

This new chip would be mostly used in portable devices like MIDs. What's really great about these new chips is that they will use 20% less power yet gain 40% in performance when compared to the current 45nm chips.

What's particularly useful about this is that those using 32nm chips will be able to transition to the 28nm ones easily, without a complete overhaul of the system. Production is expected to begin sometime next year.

Graphene may be used for 1,000GHz chips

Graphene may be used for 1,000GHz chips

Graphene might be the next material of choice for making processor chips, according to an MIT report. In fact, Graphene, a substance discovered in 2004 that consists of pure carbon, could allow for faster speeds than ever thought possible.

The current research shows that a frequency multiplier could be created, which works to double a signal and likewise doubles a processor's clocking speed. Color me impressed! This idea is not new, but it is certainly new when applied to Graphene, which possesses only an atom's thickness.

So, what's so exciting about this? Well, Graphene chips could make for processors that run between 500GHz and 1,000GHz. That's quite a leap from the current 5GHz chips, wouldn't you say? We should see a commercial version of this technology within two years, according to MIT.

Broadcom BCM4329 chip brings cellphones Wi-Fi without power drain

Broadcom BCM4329 chip brings cellphones Wi-Fi without power drain

Now cell phone WiFi access will get a lot more efficient, thanks to a new chip from Broadcom. The BCM4329 chip will be used in cellphones that have 802.11n WiFi in order to decrease the amount of power required to maintain that wireless connection.

Normally, WiFi on cellphones takes up a lot of energy. In fact, it's often thought of as a serious battery drainer. But this new chip makes it so a 2.4GHz or 5GHz band connection can occur without using as much power. It uses less power than earlier chips that could only manage the 802.11g standard and no higher.

This chip also offers up Bluetooth 2.1 + EDR, an FM tuner and a feature called space time block coding, which makes connections on the outskirts of a network more stable. The Broadcom BCM4329 chip is expected sometime in 2009, though no customers for it have been named yet.

New writing tech could bring 10x smaller processor chips

New writing tech could bring 10x smaller processor chips

Technology keeps getting smaller and smaller and now researchers at the University of California at Berkeley have happened onto a new way to write data that could result in chips that are 10 times smaller than what's currently available.  

It works by using a writing arm that's incredibly small. This arm would use lenses with plasmons to write data in a very compact fashion. With all of the data much more closely spaced together, more data can fit on a single chip, meaning chip size can be reduced dramatically.

Fake chips sold to US Military blamed for dangerous failures

Fake chips sold to US Military blamed for dangerous failures

American security forces are facing a mass examination of their hardware, as an ongoing investigation discovers that counterfeit computer chips and other devices have been sold to the US government.  According to a BusinessWeek report, recycled and fake microchips from Chinese vendors are being used - mistakenly or otherwise - in hardware distributed in America and bought, off the shelf, by the US military. 

Two separate incidents involving fighter jet malfunction are being unofficially blamed on fake chips billed as Maxim and Xicor products; the two manufacturers have denied any involvement with the shipments.  Yet another incident describes how fake routers, branded Cisco, were used by various military agencies, heedless to the fact that each could have a covert "back door" through which their makers could access classified information.

AMD is breaking up

AMD is breaking up

Last night some rumors were going around about whether or not AMD would be breaking up today, but it seems now the rumor is confirmed. The company will be splitting up and the news will be officially announced today.

A press release last night indicated that AMD would be making an important announcement today. It would involve the CEO and president of the company, Dirk Meyer and was said to be a "significant corporate announcement." This set the blogs abuzz and reinvigorated the rumors about AMD breaking up.
