Memory Circuits the Size of a White Blood Cell

[Jimmy 2004]

Chemists from UCLA and the California Institute of Technology have managed to create an ultra-dense memory device capable of storing 100 Gb (gigabits) per square centimetre, an accomplishment which could lead to much smaller and more powerful computers than we have today. The memory uses a series of perpendicular nanowires crossing over each other, with 400 silicon wires crossed by 400 titanium wires, both 16nm wide. At each crossing are approximately 300 bistable rotaxane molecules which can act as switches and therefore be used to store data in a very small space.

You gotta love honesty, add me to the list.

Even I don't really know what it means TBH... I just picked out what I could sort of understand and posted it

Essentially it has tiny bits of wire crossing each other and stores data at the exact points where they cross. I think.

Pretty soon the computers will be like one of those commercials (for the ps9) about the size of a human hair with interactive 3d technology. I love this!

"At each crossing are approximately 300 bistable rotaxane molecules which can act as switches and therefore be used to store data in a very small space."

Bistable meaning here molecules that have to stable states so 1 & 0. Basicly the wires are there just to hold the rotaxane molecules in plaze, which store the actual data. Well that and to transmit the state of the molecules. How they do that and how come there are 300 of them in one crossing goes over my head xD Can't grasp something so tiny working, so I'll join the list

If I'd have to guess more, the titanium wires are there to offer structural stability and silicon wires act as semiconductors whose electrical conductivity those rotaxane molecules alter. But I really don't know =)
