Question
1. Is it feasible to create a portable battery powered drive out of RAM that could sustain its data via the charge of a battery? From my understanding it doesn't require much power.
Combining this with drive encryption. I see this as being a highly effective method of securely transporting data, that in the event of emergency could be fairly rapidly (Around five minutes according to research at Princeton University) erased by removing the charge from the volatile memory.
2. Do you know of any current volatile memory implementation that could achieve such a result?
Explanation / Answer
This is perfectly feasible. Current RAM only holds its storage while power is applied to it, so doing that in a mobile device is no different to doing it in a computer.
And you are right - turning the power off will lose all data on the drive in a very short time frame.
Your question 2 is irrelevant. All common RAM implementations can do this. All you are wanting to do is scale down from something you could do right now with a laptop to just the RAM.
