Human memory is like a computer we haven't built.. yet. Neural circuits *are* circuits; we could built one out of pipes + pressure, metal + electricity + flaky silicon (computer memory), or rubber bands + popsicle sticks... or a computer program, or imagine it all in our minds in a series of steps and changes to parts against a grid. This is that grid. Our brains seem to use a math that's not a 0 1 like computers, but more like a 0 1 2 - ''trinary'' math. the memory cells stick to tubes through static electricity; yeah, like a balloon sticks to your hair after you rub it. Our closest computer equivilant is a CMOS chip - stores via ''NOR'' gates - its what keeps the very basic settings of our computer intact - even when it's turned off. Fact checkers among you - and if you want to see a few examples of biological logic gates - http://www.ploscompbiol.org/article/info%3Adoi%2F10.1371%2Fjournal.pcbi.1002421#pcbi-1002421-g005
