Is this April 1st?  It is called *RANDOM* Access Memory because all accesses 
take the same amount of time.  That is the nature of the hardware.  There could 
be some issues with cache hits and cache organization, but that would only occur 
in *very* special cases.

If stuff is left in RAM after the process exits, the kernel doesn't care what is 
left in memory.  It is just marked as unused.  You don't leave 'artifacts' behind.

I don't know where you come up with this stuff unless you think it is just a 
joke.  If so, it wasn't apparent.
