Never experienced that myself Ross, either I've been really lucky, or the
random address that got creamed was well above where my code sat.  EIther
way, I've been using the Dallas static ram chips (or boxes, they are kinda
big) for a while now and had great results.  Sounds like their powered socket
offers a lot of the same features.
