A Fault-Tolerant Technique for Nanocomputers: NAND Multiplexing

In order to make systems based on nanometerscale devices reliable, the design of fault-tolerant architectures will be necessary. This paper presents a novel fault-tolerant technique for future nanocomputers, NAND multiplexing. Initiated by von Neumann, the NAND multiplexing technique, based on a massive duplication of imperfect devices and randomized imperfect interconnect, had been studied wit...

Nanocomputers and Reversible Logic

An overview of nanocomputers is given, including a discussion of reversible computing techniques and an explanation of why they are necessary. 1 Nanocomputers I usually begin this talk by trying to justify why we need nanocomputers in the rst place. As Caxton Foster once said of associative memory, nanocomputers would seem to hold out the promise of sugar tomorrow to people drowing in honey tod...

Cellular Nanocomputers: A Focused Review

Research into nanocomputer architectures have increasingly attracted attention in recent years, driven by the realization that improvements in integration densities can only be sustained at an unchanged pace if new approaches are adopted. As top-down fabrication methods like optical lithography are gradually facing their technological and economical limits, alternatives are called for. Bottom-u...

Dispersion Reduction Technique Using Subcarrier Multiplexing

We have developed a novel dispersion-reduction technique using subcarrier multiplexing (SCM) which permits the transmission of multiple 2.5 Gbit/s data channels over hundreds of kilometers of conventional fiber-optic cable with negligible dispersion. Using a lithium niobate external modulator having a modulation bandwidth of 20 GHz, we are able to multiplex several highspeed data channels at a ...
