These folks use the term "CMOL" to refer to a hybrid between CMOS and MOLecular-scale fabrication. ] The CMOL concept combines the advantages of nanoscale ] components, such as the reliability of CMOS circuits and ] the minuscule footprints of molecular devices, and the ] advantages of patterning techniques, which include the ] flexibility of traditional photolithography and the ] potentially low cost of nanoimprinting and chemically ] directed self-assembly. This combination may enable CMOL ] circuits of unparalleled density ... at acceptable } fabrication costs ] Such success would pave the way for more ambitious goals. ] It is plausible that a cerebral-cortex-scale ] CrossNet-based system -- one with ~10^10 neurons and ] 10^15 synapses that would require a ~30 × 30 cm2 silicon ] substrate--would be able, after initial training by a ] dedicated external tutor, to learn directly from its ] interaction with its environment. In this case, we can ] speak of a "self-evolving" system. |
