Fujitsu doubles its non-volatile FRAM

The good (memory) ship sets sail.

Fujitsu has announced 2 Mbit ferro-electric RAM (FRAM) memory chips, twice as dense as its previous 1 Mbit FRAM. This memory technology combines the qualities of RAM with non-volatile memory such as Flash.

FRAM is similar in construction to DRAM but with a ferro-electric layer to achieve non-volatility. It has a number of advantages over Flash, which dominates the non-volatile memory market: lower power usage; faster write speed; and a much greater maximum number of write-erase cycles; up to ten billion, equivalent to writing 30 times a second continuously for ten years. It can also store data for ten years without a battery.

Flash's disadvantages include: high program and erase voltages; slow programming speed; limited write-erase endurance. Its advantages are high storage densities - now in the multiple gigabits area - and a low cost per storage bit.

Flash and FRAM characteristics make FRAM suitable only in applications that need its power efficiency, write speed and prolonged write-erase cycle count. These include car navigation systems, multi-function printers, and measuring instruments. If the power supply to measuring instruments fails, data can be written to FRAM at high-speed to prevent its loss.

FRAM's primary competition comes from MRAM and PRAM. Fujitsu and Ramtron produced 1Mbit FRAM chips in 2006. Fujitsu says its 2MBit FRAM is the largest capacity in volume production, a reference to Freescale Semiconductor which started limited production of 4Mbit FRAM in summer, 2006.

Fujitsu's 2 Mbit FRAM chips, using the same packaging as its 1MBit chips, are available now, with sample pricing of 2,000 yen and a production capacity of 200,000 chips per month.

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.
