Will heating the platters beyond curie temp make disk-splicing impossible?

Is it possible to build the memory chip in such a way that when the power is offed, it only takes 1/100 second for all the data to be completely lost even at the quantum level?

Is there any other way to prevent this burn-in issue?

Not really. The capacitors aren't discharged sequentially. The charge on a capacitor will leak 63% in one TC, sure, but they will all leak to 37% in that same TC. If the threshold voltage is 50% +/- 20%, all the cells will be below the threshold in just a little over a TC.

on.

Not if it needs to be functional with useful refresh rates.

It is NOT burn-in. It is residual charge. See other posts on longer retention times.

Let's say that after the power supply is cut-off from the volatile RAM chip, the RAM chip is heated to the hottest it can get without suffering any physical damage. Will this speed up the rate at which data is lost?

Unless you can reliably get temperature regulated heated air on the memory module in a fraction of a second, it won't much matter.

It is called a BIOS call.

A slate bar works great for erasing digital media. Cheap, fast, legal, and a good way to say "bye" to the malfunctioning hard drive that caused you grief.

If you want to look it up, the official name is "SECURITY ERASE UNIT".

On Linux, you can issue the command with "hdparm --security-erase ...".

Astounding. I will be pursuing this.
