With respect to 3d storgae...
...it is definitely not out of the question and is definitely a future contender for storage.
Most data storage mediums are currently 2D - tape, flash, hard disks, DVD, CD...
Generally, when we say 3D or 2D we are referring to the dimension of the array of points where each 'bit' is stored rather than the number of values each 'bit' can take . Something at each point in the array can then be changed in some way to represent, as someone above put it, a 0 or a 1. For example, in a hard drive, you have a magnetic film (2D), and small areas (bits) are magnetised in a certain direction, with for example, up representing 1, or down representing 0.

Memory chips are made of crystals; crystals of silicon. Silicon exhibits the proper semiconductor properties only in its crystalline form. Pure silicon crystals (intrinsic silicon) has poor conductivity since the outer shell electons are bound into the crystal lattice. However, the addition of a small amount of impurities (doping) produces spots where the impurity atom fits into the lattice but either has an extra electron, or a space missing an electron. These extra electrons or spaces (holes) can move more freely in the lattice and raise the conductivity of the material. Transistors are formed when the differently-doped silicon materials are joined, and these transistors can be used to form memory elements.

The problem with crystals is they are a 3 diminsional shape and computer commands only come in 2: 0,1.
The problem would be finding a way to store information in 3 dimisions, when you can only fill 2 diminsions, but anything is possible.

If you are talking about 3D storage technique, I think the next possible thing is holographic storage. Go search for hologram harddrive, don't think it's physically realisable yet.

I recall reading something about that years ago. Google it.
