Samsung unveils 64Gbit flash memory chip

Company expects technology to appear in its storage cards by 2009

Samsung Electronics announced that it has built a 64Gbit NAND flash memory chip.

The new flash storage device utilizes 30-nanometer processing technology and was developed using Samsung's self-aligned double patterning technology (SaDPT), said Samsung officials.

The company said it plans to start manufacturing 30-nanometer 64Gb NAND flash devices during 2009. Samsung has already applied for as many as 30 patents for the new flash memory chip, officials said in a statement.

By combining a total of 16 separate 64Gb flash devices, businesses can create a 128GB flash storage device capable of holding up to 80 DVD movies or 32,000 MP3 music files, noted Samsung.

While some analysts have forecasted of somewhat sluggish NAND demand in 2007-2008, Gartner Inc has predicted that sales of 64Gb NAND flash and other higher density flash storage devices could reach US$20 billion by 2011.

Samsung said that its new double-pattern technology creates a wider-spaced circuit design of the target process in the first pattern transfer, and fills in the spaced area more closely with its second pattern transfer on the chip.

Samsung said it has also designed and constructed a 32Gb NAND flash storage chip using the same technology as its new 64Gb offering.

Windows 10 for Business / Dell XPS 13

I’d happily recommend this touchscreen laptop and Windows 10 as a great way to get serious work done at a desk or on the road.

Ultimately, I think the Windows 10 environment is excellent for me as it caters for so many different uses. The inclusion of the Xbox app is also great for when you need some downtime too!

Windows 10 / Lenovo Yoga 910

For me, the Xbox Play Anywhere is a great new feature as it allows you to play your current Xbox games with higher resolutions and better graphics without forking out extra cash for another copy. Although available titles are still scarce, but I’m sure it will grow in time.

First impression on unpacking the Q702 test unit was the solid feel and clean, minimalist styling.

For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.
