Mitsubishi Electric, Rambus ink licensing pact

Under the terms of a patent license agreement signed between the two companies, Mitsubishi has agreed to pay Rambus royalties for technologies used in SDRAM (synchronous dynamic RAM) and Double Data Rate (DDR) SDRAM memory chips, as well as in controller chips that directly interface with these types of memories, Rambus said in a statement. In addition, the agreement calls for Mitsubishi to pay a license fee for the entire package.

Financial terms of the agreement were not disclosed, but Rambus said that the royalty rates Mitsubishi has agreed to pay for DDR SDRAM chips are higher than comparable rates for the US company's proprietary RDRAM (Rambus DRAM) technology. Rambus has signed similar agreements with six other memory chip makers, including Hitachi, NEC, Samsung Electronics and Toshiba.

Other memory makers, including South Korea's Hyundai Electronics Industries, Munich-based Infineon Technologies and Micron Technology, from the US, have refused to acknowledge Rambus' patent claims and are fighting the company's royalty demands in courts.

For Rambus, which is a pure technology developer and does not produce any products itself, the royalty agreements it has signed with companies over SDRAM and DDR SDRAM will ensure a steady revenue stream whether or not its proprietary RDRAM memory technology is successful.

Chip giant Intel's latest Pentium 4 processor currently is available only in PCs featuring RDRAM, while Intel competitors such as Advanced Micro Devices and Taiwan's Via Technologies to date have backed the competing DDR SDRAM memory technology.

The Pentium 4, which was launched in November, is expected to give a boost to sales of RDRAM memory chips, according to backers such as Seoul-based Samsung.

Samsung, the world's largest supplier of RDRAM chips, projected in November that the worldwide RDRAM market would grow to about $US9.2 billion in 2002, up from approximately $US1.7 billion in 2000.

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.
