That's is not what HP is saying:

Existing computers store their operating systems, programs, and files on either a hard disk drive or a flash drive. To run a program or load a document, data must be retrieved from the hard drive and loaded into a form of memory, called RAM, that is much faster but can?t store data very densely or keep hold of it when the power is turned off.
HP plans to use a single kind of memory?in the form of memristors?for both long- and short-term data storage in The Machine. Not having to move data back and forth should deliver major power and time savings. Memristor memory also can retain data when powered off, should be faster than RAM, and promises to store more data than comparably sized hard drives today.
And IIRC as of today the number of write cycles is ~100million for a memristor (5000 for flash!) so I would say there's no need to replace devices every 2 year and there's not even wear-leveling needed.
The real problem is that some researcher say, that a memristor cannot work (and will never be working) because of physics. Lets see what the future holds

They've repeatedly mentioned it in comparison to system memory (which currently means 4-32GB for the great majority), and several times in comparison to SSDs (which currently means 4GB-1TB). I would be shocked to see any memristor drive at 1TB+ and under 1000$ in less than three years.
@droste: 100 million writes is nothing for ram. It's not enough to replace ram for any conventional architecture. We'll see what they come up with in the next few months.Last edited by liam; 28 December 2014, 06:15 PM.

And with HPs new architecture there's no need for traditional heavy read/write RAM for caching hard disk data. You just read the stuff you need from where it already is, so writes are really only needed if information changes.
More recent articles are also not mentioning the write endurance. Maybe it's higher or even unlimited with new materials. I can't find recent information (especially regarding HPs stuff) anywhere.

The first 733Mhz Itanium Merced core had severe issues out-performing a 1.7Ghz Pentium 4 Willamette core. In theory, Intel could slowly force the market into adopting IA64 by keeping P4 32bit-only, but the Atlhon64/Opteron left them not choice. (And the lackluster performance of the McKinley/Madison cores didn't really improve things)
Sure, by 2006 the performance was acceptable, but by then both the Xeon and the Opteron shoved it into a very small market segment (Super-high-end servers) and most of the Itanium server manufacturers left the architecture.

they contracted a Russian specialist team to do the job, when they figured out that the situation was very badly.
The team was from elbrus, which are specialist on sparc, and high performance computing.
But it turned to be a very late decision, and the world wanted to get rid of it, because of the prices, I think...
