What's the advantage of memristor-based storage, exactly?
If it's cheaper to make, then sell storage at a price that undercuts the competition but still makes a better profi.
If it's more reliable, then sell storage at a higher price with a better warranty.
There's no sensible scenario where memristors are ready to go but they don't want to sell any memristor products yet because it will hurt existing sales. Either they can make a better product, or they can't, and if they can't make a better product then the stuff simply isn't ready.
