off topic: volatile USB stick available

[Andre Tann]

Hi all,

does anyone happen to know about a USB drive or similar that has a 
volatile memory?

Scenario:
I want to place a LUKS key on that stick. The stick is connected to a 
USB port with permanent power.

Then the server could be rebooted or powered down/wake on LAN, and still 
be able to automatically open the LUKS partition.

But once the machine looses power, the USB drive would forget all data, 
and the partition cannot be mounted automatically anymore on boot.

That's kind of a security measure.


Any ideas about such a stick? Or about other ways to achieve the above?
