Memory's endpoint (nanotechnology)

Nanotech... use in computer Architecture... the possibilities are growinng ever smaller...
The IBM Millipede project...
The mechanical synapses of IBM's Millipede memory device form a grid - a 64 by 64 array of cantilevers. each one equipped with a silicon tip (bottom)

This narrows to only a few nanometers in diameter. To write data the tip heats up and, as the cantilever darts back and front pockmarks a thin polymer sheet. to read data, a separate sensor detects the presence or absense of a pit. And to erase data, the silicon tip gives a hole a secnd hot tap. which seemlessly eliminates the pit.
