Elpida develops thin memory device for tablets, phones

The devices can be used to pack more memory into thinner phones and tablets, Elpida said

Elpida Memory and subsidiary Akita Elpida Memory said Wednesday that they have developed technology to mass-manufacture a four-layer DRAM package just 0.8 millimeters thick that can be used to pack more memory into thinner mobile phones and tablets.

The new package shaves off 20 percent from current 1.0 mm four-layer packages.

The Japanese DRAM maker claimed that the 8-gigabit package, consisting of four low-power-consumption 2-gigabit DDR2 (double data rate, second generation) Mobile RAM chips, is the thinnest device currently in the DRAM industry.

The company's Mobile RAM is synchronous DRAM for mobile applications, and features lower power consumption and low-voltage operation.

Elpida said the next development step is an ultra-thin 0.8mm PoP (package-on-package) consisting of four layers of 4-gigabit products.

Volume production of the four-layer 0.8mm PoP products is expected to begin in the third quarter of this year, the companies said.

PoP is an integrated circuit packaging technique that reduces the mounting space and wire length on devices by stacking multiple packages.

Customers are already using two-layer 0.8mm 8-gigabit packages because existing 1.0mm-thick four-layer PoP products are too thick, Elpida said.

Demand for DRAM generated by tablets will rise by a factor of nine in 2011, fueled by booming sales of the iPad, combined with the arrival of more competitive alternative products, research firm IHS iSuppli said in June.

Tablets this year will consume 333.7 million gigabits of DRAM, up from 37.3 million gigabits in 2010. DRAM demand from tablets will soar to 1.1 billion gigabits in 2012, reaching 5.8 billion gigabits by 2015, iSuppli said.

A smarter way to print for busy small business owners, combining speedy printing with scanning and copying, making it easier to produce high quality documents and images at a touch of a button.

I've had a multifunction printer in the office going on 10 years now. It was a neat bit of kit back in the day -- print, copy, scan, fax -- when printing over WiFi felt a bit like magic. It’s seen better days though and an upgrade’s well overdue. This HP OfficeJet Pro 8730 looks like it ticks all the same boxes: print, copy, scan, and fax. (Really? Does anyone fax anything any more? I guess it's good to know the facility’s there, just in case.) Printing over WiFi is more-or- less standard these days.

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!

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.
