Abstract
An architecture for nanoscale electronics is disclosed. The architecture comprises arrays of crossed nanoscale wires having selectively programmable crosspoints. Nanoscale wires of one array are shared by other arrays, thus providing signal propagation between the arrays. Nanoscale signal restoration elements are also provided, allowing an output of a first array to be used as an input to a second array. Signal restoration occurs without routing of the signal to non-nanoscale wires.
Claims62
An architecture for nanoscale electronics comprising:
- arrays of crossed nanoscale wires, each array comprising a plurality of crosspoints between nanoscale wires, the crosspoints being selectively programmable, wherein nanoscale wires of one array are shared by other arrays, thus providing signal propagation between the one array and the other arrays;
- nanoscale signal restoration elements, allowing an output of a first array to be used as an input to a second array, wherein signal restoration occurs without routing of the signal to non-nanoscale wires;
- and
- nanoscale driving devices of crossed nanoscale wires for selectively programming at least some of the crosspoints.
The architecture of claim 37, wherein the FET-type crosspoints are programmed during fabrication.
A method for assembly of arbitrary boolean logic computations at sublithographic scales, the method comprising:
- providing sublithographic-scale arrays performing a predetermined logic function;
- providing signal restoring devices for the arrays, the signal restoring devices performing signal restoration at sublithographic-scale level;
- interconnecting the arrays;
- and
- providing sublithographic-scale driving devices for programming the sublithographic-scale arrays so as to allow customizing the arrays to perform the logic function and signal routing.
