Cosmic rays pass through us all the time - I don't know offhand the cosmic ray flux. Like Joe I did the cosmic muon lifetime experiment at University. I always wanted to do an undergraduate project using CMOS RAM as a radiation detector - read and write bit patterns to it, and see if the results match.
Funny, I did it too. One of my favorite undergrad experiments, proves relativity theory, and there is the always muon catalyzed fusion to muse over as well. I don't think memory is all that unstable, especially down where I live. In Denver, maybe. I think you need a lot of RAM, for a long time, to see a lot of radiation induced errors, or a source of high energy particles. rgb
