Turns out dynamic RAMs can be read once (destructively) after they
are turned off.  For this reason, (among others) all the computer
equipment that goes into "the vaults" IS destroyed.  This causes
some problems, though, when you need to debug something in the vault,
since you can't take it out, you have to take in all the test
equipment, and then you can't take the test equipment out again...
