Default [TechReport] Intel, Numonyx announce phase-change memory breakthrough
Quote:
Get ready to say goodbye to system RAM and flash-based solid-state drives... eventually. After several years of joint research, Intel and Numonyx, the chipmaker's former NOR flash division, have announced a "key breakthrough" in the development of phase-change memory (PCM): a 64Mb test chip that "enables the ability to stack, or place, multiple layers of PCM arrays within a single die."

As the two companies point out, phase-change memory combines "many of the benefits" of system RAM and flash memory. Like system RAM, PCM can write single bits or bytes instead of whole blocks, and it can do so with very little latency and similar read bandwidth (but lower write bandwidth). PCM is also non-volatile, meaning it remembers data even after the device is powered off, just like flash memory.

With this breakthrough, Intel and Numonyx expect to make PCM considerably cheaper to produce than before—there was talk in the conference call of a cost structure much like that of NAND flash memory, which powers today's solid-state drives, with similar density increases over time and without compromised performance. The two firms see the potential for "collapsing" existing memory types (such as NAND and DRAM) into PCM in future devices.

Can't wait until this finally makes its way into consumers' hands!!!

So this is supposed to replace both ram and HD?
I'm confused as to why this is such a huge breakthrough...is it super small or what?

If I readed right, SSD prices should go down with this new breaktrough.

no it won't. SSD's use NAND Flash tech, while this breaktrhough is for NOR Flash.

I think this is really a huge breakthrough because, if these phase-change memory come out, then we won't need memory and HD, just a PCM which will be as fast as a memory and stores the data when your PC is switched off.

But when will we this thing in our PCs? 5-10 years later?

That statement must have messed me.

No way it would be mainstream in 5 years. If everything works out, 10 years before it can compete with flash. That said, this technology should be far far superior to flash in terms of speed, and will make for some lightning quick mobile devices.

Well... SSD just means Solid State Drive, it doesn't mean it has to be built using NAND tech. Could a SSD not be built out of NOR Flash?
