The application of a boiled memory stick is puzzling. However, I'm certain any time traveller, who finds him/herself accidentally quartered or boiled alive, will appreciate that their data on 'medieval England' is save and sound...:)
As has been stated, the use for a memory stick that survives conditions that would terminate its owner would appear to be limited and as far as the buyer is concerned academic. It's the same as those watches that tell the time under a 100 metres of water, unless you're a diver, or want to know the exact time at which you drown. Why bother ?
The basic (silicon) semiconductor elements will not only survive but operate at temperatures above 100oC. Many years ago I ran a simple transistor circuit, operating as a temperature sensor, continuously for several weeks at 100-120oC.
In practice the survival of more complex electronic components is limited by the melting, deterioration or decomposition of other elements eg plastics, adhesives, circuit boards etc.
In addition, the maximum operating temperature is often much lower as a result of the heat generated in a complex component - a microprocessor, for example - which can raise its internal temperature by some tens of degrees.
Clearly, a memory stick is near optimum in that it is little more than a simple array of semiconductor memory chips in a ruggedized container.
