For those too lazy to do the math:

128 bits = 16 bytes = $0.10

8192 bits = 1024 bytes = 1kb = $6.40

A megabyte of this would cost over 6 grand, and probably would take up a lot of surface area :) If the current product is approx 1cm squared (a guess), your $6 1kb one would take up 64cm squared, which, according to wolfram alpha is about half the size of a passport or 1.5x the size of your credit card.

One more step toward a fully self-replicating reprap.
