Victor6799,
Have you exhausted all possibilities like the obvious ones.
Internet connection, spyware software or some kind of hardware malfunction?
If these chips have a built in receiver/transmitter the transmitter would have to be very close possibly only feet away. The digital switching at the memory controllers is an unwelcome environment for any type of robust communication via an antenna especially an un-optimal one that might be in an IC package.
Ask yourself this question?
What is so important about what you are doing that would warrant such a clandestine action by someone else?
I would guess that unless you are in the state department or using some top-secret defense department computer you probably are not being attacked through a radio remote interface. Then again you would not be posting your question on a public forum if you where. I am not trying to be rude but you may be avoiding some other more common hacking techniques.
