See EMMA project

http://www.imec.be/EMMA/

See Versatile project (Intel & ST, EU funding. )
Crossbar "vertical stacked resistive" with eg Zinc oxide diodes for access.
ZnO used due to high process temperatures which bar usual materials
when layer on layer methods are used.
"Only" 5 micron at present. Gains are as much from vertical stacking.

Samsung working on similar.

Bulk.
- Quantum computer stuff - more states than you can fit into "reality".
- Mayhaps 'bits' of light slowed to m/s range and packed in tight.
- "A few atoms" TM per cell stuff.
- Buckminsterfullerene seems to keep turning up new attributes. Must
be good for high density memories too.
For real volume Flash has a way to go to outcompete electromechanical
storage. What WOULD alien visitors thin? !!!! "You use mechanically
rotating stuff !!! ?"
- Phase encoded light in optical fibre? (Even at TerraHertz range you
get ~ 100s of  cycles per foot in free space. Play Bose-Einstein
tricks with it and you may get "rather more".

E&OE, YMMV, do not bend fold spindle or mutilate. TTFN.

There are some embedded SD solutions out there, but I don't think they've
caught on quite as much.

Also, when you start striping data across multiple flash devices, you want
your own control logic, not something that's optimized for a single device.
Since this is what's done now in SSDs, raw flash/NAND is much preferrable to
solutions with integrated "intelligence"

FRAM is nice. If the cost goes down, I think it will gain quite some market
share in the MCU segment.

Huh?  Isn't it the other way around?  MMC was first, and SD/SDHC added  some pins and parallel modes for faster access?  MMC cards seem to  have all but disappeared, though in most cases the SD cards are  backward compatible.

The SD licensing issues ARE annoying.
