Thanks for that.

Here are two useful links i discovered while googling items in your explanation. I post them here for convenience to both others and myself (so i'll know where to find them in the future, if need be):
  1. Semiconductors Without the Quantum Physics (or not so much that you would notice)

  2. Solid State Drives Data Reliability and Lifetime (PDF whitepaper)

It seems that the problem "insulating" material is SiO2 (silicon dioxide, aka silica), a special glass of some sort. So basically, the semiconductor components (FETs) remain more or less intact... but the loss of insulation (due to *writing* any data which toggles zeros and ones) renders the overall device increasingly useless for non-volatile storage. What a shame.
