Hola amigos, from 4DS website.. Reram nvm or storage class memory uses less power because it is non volatile, I.e able to retain data whilst power is off.. $cost to produce is the single biggest factor as quoted by Jim Handy, the savings once in operation only add to the potential sales pitch..

Retention is everything in the space close to NAND Flash, while reaching a higher speed than NAND Flash is the opportunity for which system companies may be willing to pay a higher price per gigabyte. Whatever endurance this results in may be acceptable.

Speed is everything in the space close to DRAM, while reaching an endurance as close as possible to DRAM is the opportunity, especially if this reduces the need for more expensive DRAM in systems. Whatever retention this results in may be acceptable.

The main reason that retention is far less critical than speed and endurance is the space close to DRAM is that DRAM is essentially a volatile memory. Its contents need to be read and written back (refreshed) every 60 milliseconds and any retention better than DRAM saves power.

The reality is that a Storage Class Memory with a retention of just one day is an astonishing 1.5 million times (or 6 orders of magnitude) better than DRAM retention. A Storage Class Memory with a retention of 1 week, 1 month, or 1 year further boosts this to 10 million, 44 million, and half a billion respectively.

The biggest opportunities are always where the pain is the highest and that is in the space closest to DRAM. The ultimate market demand is therefore for Storage Class Memory with DRAM speed, the highest endurance achievable with this speed, a cost per gigabyte closer to NAND Flash, and a pragmatic retention far superior to DRAM retention.
