Going the way of the Dodo
Crossbar adds that its technology can retain data for up to 20 years, compared with the standard one to three years with NAND flash. According to the company it has achieved a "simple and scalable" memory cell structure, consisting of three layers.
The structure means cells can be stacked in 3D, squeezing terabytes of storage capacity onto a single chip. If Crossbar gets its way there will be a wave of faster enterprise and consumer devices with huge memory capacity.
CEO George Minassian said that a Crossbar array has achieved all the major technical milestones that prove our RRAM technology is easy to manufacture and ready for commercialisation. He claimed that it was a watershed for the non-volatile memory industry. Obviously RRAM will take down the NAND flash market, which is used in SSDs because it solves the problem of limited write life.
RRAM stores bits by creating resistance rather than storing electrical charges. That requires less energy consumption and, depending on the material used, means more write life and capacity. While the technology has been there barriers to commercial development entail achieving the speed, endurance and retention of other memory technologies.
Crossbar still faces the issue of making its chips, but the company did say it had built a working prototype, in readiness for the first wave of production.
Note to self - don't trust flash-based data archives.
Yeah, I'd missed that little tidbit as well.
Rreally?
Either that or don't trust claims by Fudzilla and some company that claims a better technology.
I'll believe it when I see it.
Due to its simple three-layer structure, Crossbar technology can be stacked in 3D, delivering multiple terabytes of storage on a single chip. Its simplicity, stackability and CMOS compatibility enable logic and memory to be easily integrated onto a single chip at the latest technology node, a capability not possible with other traditional or alternative non-volatile memory technologies.
See #5.
Me too. And in two+ years, we'll find out keeping duplicate copies on non-flash-based media was a waste of our time.
Less talk, more action.

Yeah, you can only write to a flash device so many times. They have “wear leveling” algorithms so that the same data being written doesn’t always write to the same spot in flash, this minimizes the issue. Flash is also more sensitive to heat, it can go bad just sitting there.
Will the codexes required to write the files today be available in 20 years, or will they be historical curiosities?
OTOH, will a Carrington Event render all of this moot?
I’m holding out for phase-change memory.
