Samsung now producing DDR 2.0 NAND flash, touts 3X performance gain

New flash is made using 20-nanometer circuitry

Samsung Electronics announced that it is now producing high-performance DDR 2.0 multi-level-cell (MLC) memory chips based on its smallest 20-nanometer (nm) circuitry. The chips boast a performance improvement of three times over the company's current chip technology and have 64 gigabits of capacity, twice what Samsung had been producing with DDR 1.0 technology.

The chip will be used in mobile devices such as smartphones, tablets and solid-state drives (SSDs), Samsung said.

Equipped with a toggle DDR (Double Data Rate) 2.0 interface, the new 64Gbit chip can transmit data at a bandwidth of up to 400Mbit/sec.

DDR NAND flash comes in two forms: Toggle Mode from Samsung and Toshiba; and ONFI NAND, from the Open NAND Flash Interface (ONFI) working group.

The ONFI protocol is used by flash manufacturers such as Intel, Micron, SanDisk. Hynix and Spansion. In March, the ONFI working group announced its 3.0 specification for the DDR 2 interface with up to 400Mbit/sec throughput.

DDR 2.0 provides a 10-fold increase over 40Mbit/sec Single Data Rate (SDR) NAND flash in widespread use today. The new flash memory also triples the performance over 133Mbit/sec toggle DDR 1.0, 32Gbit NAND flash memory, which Samsung and Toshiba have been producing since 2009. "With this 20nm-class, 64Gbit, toggle DDR 2.0 NAND, Samsung is leading the market, which is evolving to fourth-generation smartphones and SATA 6Gbit/sec SSDs," Wanhoon Hong, executive vice president of memory sales & marketing for Samsung Electronics, said in a statement.

Samsung said its high-bandwidth toggle DDR 2.0 is expected to better support the ongoing shift toward advanced interfaces, as more mobile and consumer electronics devices requiring added performance and higher densities adopt new interfaces such as USB 3.0 and SATA 6.0Gbit/sec.

Further, the new 64Gbit MLC NAND chip offers an approximate 50 per cent increase in productivity over 20nm-class 32Gbit MLC NAND chips with a toggle DDR 1.0 interface (which Samsung started producing in April 2010) and more than doubles the productivity of 30nm-class 32Gbit MLC NAND.

This small mobile printer is exactly what I need for invoicing and other jobs such as sending fellow tradesman details or step-by-step instructions that I can easily print off from my phone or the Web.

Microsoft Office 365/Dell XPS 15 2-in-1

I’d recommend a Dell XPS 15 2-in-1 and the new Windows 10 to anyone who needs to get serious work done (before you kick back on your couch with your favourite Netflix show.)

Brother PT-P750W

It’s useful for office tasks as well as pragmatic labelling of equipment and storage – just don’t get too excited and label everything in sight!

The Brother MFC-L8900CDW is an absolute stand out. I struggle to fault it.

MSI GT75 TITAN

I need power and lots of it. As a Front End Web developer anything less just won’t cut it which is why the MSI GT75 is an outstanding laptop for me. It’s a sleek and futuristic looking, high quality, beast that has a touch of sci-fi flare about it.
