Where can I find my preferred laptop?

Would Twin-Transistor RAM also have this problem?

It doesn't need a hardware solution. Mr. Skeptic's solution:

 

Hm, it seems to me that there should be software to randomize ram.

 

...would be just fine. Before powering down, overwrite the entire memory with entropy data and you're totally fine.

 

But still, "security" is an extremely vague requirement. What exactly are you trying to do?

I'm asking just out of curiosity.

 

Would Twin-Transistor RAM have a shorter period of data remanence [when offed] than other forms of volatile RAM?

 

I think the answer is yes because TT-RAM doesn't have any capacitors. It's able to perform capacitance without capacitors.

Just a cursory scan seems to reveal the answer is: no.

 

"This effect causes capacitance to build up between the transistors and the underlying substrate, originally considered a nuisance, but here used to replace a part outright."

It has capacitors, it's just the capacitor is the substrate and not a specific component dedicated to the task.

Just out of interest, what form of volatile RAM has the shortest period of data remanence when the power is offed?

I don't know, but if you randomize the contents of the RAM in software before powering down the system it doesn't really matter: the data left in memory when the system is powered down will be random garbage.
