DRAM had more persistent imprint of information that was sitting in it, which appears much harder to destroy than information on hard drive.
well aware of that. 30 years ago a friend and I built a specialized video card for a consulting project.... discovered on the prototype that we could power it down, go home, come back the next day, and power it up, and sufficient image remained in the DRAM to be totally recognizable. sure, it had 'noise' bits all over it, but whatever was on the screen the day before was still visible.
This is amazing! That is what distinguishes experts from us mortals: what we just learned by reading they saw themselves (sometimes quite a while ago)! On the other hand, why I'm so surprised? This is why they can answer any of our questions on this list in a split second.
Still, I'm very impressed!
