Samsung releases 1-Gbit DRAM chip with 512-pin wide I/O interface

Feb 23, 2011 by Katie Gatto weblog

(PhysOrg.com) -- Samsung Electronics announced the development of a 1-Gbit DRAM chip. It features a 512-pin wide I/O interface that is designed for a variety of mobile applications including smartphones and tablet PC's.

In order to boost the data transmission the chip uses 512 pins for the data input and output. When we compare this to the previous generation of mobile DRAMs, which used a maximum of 32 pins, we can see that a significant improvement in the of is expected.

In case you do not have an active imagination the I/O 1-Gbit WIO DRAM can transmit data at a rate of 12.8-Gbytes per second, while reducing the by approximately 87 percent. The bandwidth that this chip is expected to handle is estimated be about four times that of LPDDR2 DRAM, which runs at approximately 3.2-Gigabytes per second according to Samsung. If you include the pins for the commands, the power supply and its regulation the WIO DRAM, it is designed to have ip to 1,200 pins.

Samsung was a bit sketchy on the details, with no indications give as to whether or when the company intends to offer the 1-Gbit WIO DRAM as a packaged part or for commercial use or as part of a bare die in multi-chip packages. They were also not giving a great deal of information about when engineering samples of the 1-Gbit WIO DRAM would be made available or when the chip will be in volume production for use in devces.

As a follow up to this WIO DRAM launch Samsung has released plans for a 20-nm class 4-Gbit WIO mobile DRAM which will become available at some point in 2013.

Yeah...at this point it becomes pointless to buy a new computer or smart phone unless your previous one is broken beyond repair.

Why buy one now, when in a year they'll be double every statistic?

I feel the same way. I've yet to make the leap to a smartphone, but every time I start to consider, I see one coming out in a few months that makes me want to wait. I'm intrigued by Windows Phones because I love the Zune music service, but I'm constantly shown stuff on Android phones that I really like. All this conflict and that doesn't touch the hardware side of things...

Go look for the videos on TI's OMAP5 platform. if anything will convince you to want to wait OMAP5's promise of 100x performance improvement should do it.

Or even better are the Series 6 PowerVR Chips being developed by Imagination Technologies. HD Video at 120 frames/sec on a handheld device. Not to mention gaming...I still remember my first cell phone, a 2 pound brick from Motorola.

Briefly looked that up, and it is impressive. Where did you get 100x though? I see 3x general processor performance. Do you have a good link?

Because when it finally does come to market, you'll be paying a premium for it and if you wait a little longer, something x times better will be just anothor year away, so why bother buying then? Ultimately, you will never but anything because there will always be something better on the horizon.

My philosophy is, buy something that's relatively new and powerful and hang on to it longer. I tend to hang on to my PC builds for around five years or more.

The figures of 75-100x improvement have been quoted in their recent press releases. Google OMAP5 and choose video and prepare to be amazed.

Which is perfectly fine and sensible if you can live without one. If you don't really need it now, why buy something that isn't very good?

"Futureproofing" as it's called, and it's ultimately pointless. In computers, for half the price you get 80% the performance than buying the top end parts.

That means you're essentially stuck with a computer that cost twice as much, for twice as long for a temporary gain in performance that is surpassed in a year. That means others are using computers that are cheaper and faster than yours on average simply because they buy the budget version and replace it every two years.

Who ever said anything about buying stuff that you don't need or that wasn't any good?
"Futureproofing" as it's called

No, it isn't - it's certainly not what I was talking about. It's impossible to 'future-proof' computers or electronic gadgets. The best you can do is to maximize their useful lifetime, which was my point.

You obviously didn't read what I said, or rather, read into it what you wanted to.
