We Can Remember It For You In Tiny Increments

I was reading about memristors, particularly how they can supposedly store information more compactly and with less (which is to say no) power. I wondered if I could make something that would simulate that to see how it worked and compared with the original. But first, I need to make a model of the original, transistor-based one-bit memory.

So this is an SR flip-flop built entirely using basic components like transistors rather than slightly-less-basic IC NAND gates.

This schematic is pretty big and scary, but it’s actually pretty simple. There are three “columns”. The left is just to handle the momentary switches. The right is basically logic probes to show the state of the memory. The middle is two NAND gates, crosslinked. (I might have S and R switched. Also, I didn’t label any values or part numbers because I don’t think they are too vital for the most part.)

And here it is in action

(PS: I hope that worked. I’m hosting this video myself via an HTML5-enabled plugin that can fall back to Flash. Supposedly. And I also just realized that hosting an N MB video file could screw up my hosting provider limits or something. Well, we’ll see.)
