This is utterly brilliant! (The generalized pattern is that you have two devices, one which trades off feature X for feature Y, the other which trades off feature Y for feature X... now find (or create!) the currently non-existent device in the middle of the spectra, which balances features X and Y...) This article makes a LOT of sense if you understand how DRAM and FLASH implement memory, but with different underlying phenomena of physics -- well this could be looked at as a quest to find a harmonious point between both sets of different physical phenomena (using both, or some third derived law for the end product)... I wish you a lot of luck in that quest!
