The move, which cannot be carried out remotely, exploits a
little-known vulnerability of the dynamic random access, or DRAM,
chip. Those chips temporarily hold data, including the keys to modern
data-scrambling algorithms. When the computer’s electrical power is
shut off, the data, including the keys, is supposed to disappear.


I heard that before, but thought it is a hoax considering the fact DRAM
cells are being refreshed quite often (every 64ms?). Anyone tried that?
