Combining NAND Flash with ReRAM, the magical union consumes 93 percent less power and lasts nearly seven times as long as pure-NAND products. Despite the high cost of ReRAM, if it enables data centers to save on continuously replacing worn-out SSDs, and could very be rapidly adopted if worked into a commercial system.

I see a new future to soon to be cheaper, bigger, and faster SSD's. Eventually we may see SSD's replace RAM as the speed and latency of ReRAM matches (and exceeds) that of current DRAM. I would expect prices of ReRAM to drop soon after its mass-market introduction due to it's simplicity of design versus transistor based NAND.

The problem is that SSD prices with this type of NAND will cost extremely expensive. It might be like when SSDs were first introduced, or at least the higher cost of enterprise level SLC NAND solid state drives.

Silly idea...I want a drive made of DRAM with a power off mirror to dump things only when turned off. Essentially, why invest in tech that is not going to survive constant writes and reads when we have one that can while being faster? Practicality sucks right now but it's only because it's not being looked into.

So what extra hurdles would ReRam have to overcome that SLC NAND didn't when it was introduced? Really I don't see why it would take longer to become a part of the market than when SSDs were introduced.

SSD won't replace DRAM in the coming years, for RAM is still significantly faster than SSD.

PCIe DRAM SSDs exist and have their place in the enterprise market. They use commercial, replaceable DIMMs. They have a battery to save data when a system is off, but it doesn't last long; it's mainly there to last through reboots.

Still basically if a computer had fast enough storage it could use part of that as memory rather than having dedicated memory and storage devices. I feel that ReRam has the potential to head into that direction and not just for the enterprise market. Memory has been stagnating for some time now as we are still waiting for the arrival of DDR4. Even then I am not sure if current software can make good use of the speed boost or if the CPU can process the data quickly enough for the additional speed (2400MT/s) to be noticed. Maybe in 5-7 years technology like ReRam will catch up with DRAM in terms of speed and latency.

The computer (related) industry always does this kind of stuff. You guys should know this by now. You probably do. Someone is always talking about how great something is, before the next gen of the old version even comes out. When in reality, we don't see this new, great thing for 10 years.
