On the advent of the memristor

[spacewoozl]

The first question you might ask is, "what's a memristor?" Basically, it's a solid state device that alters its resistance based on the most recent voltage applied to it. In its fundamental form, it can be used as a digital switch. That functionality is a one device, drop-in replacement for about 10 transistors in a CMOS latch (non-volatile digital

I suppose that depends on your definition of accuracy. WW2's Nordon Bomb Sight was in essence an alanlog computer (mechanical, however). It was by far, the most accurate bombsight in the world at the time. They still couldn't hit a 2 acre target more than 50% of the time.

These "omg, synapse circuit" people spin the lack of precision as a positive: built in "fuzzy logic" (if you're keen on late 80s buzz phrazes).

On the other hand, analog has the potential to much faster, as parallel processing is a natural extension of the circuit philosophy. The same circuits will require feed-back loops inside feed-back loops - creating a sort of rudimentary learning system on the circuit level.

*shrug* That's a long way off, though... it is however, the dierection that many in HP want to go.
