Wilson Dept. of CS, 256-80 California Institute of Technology Pasadena, CA 91125 andre@acm.org ABSTRACT How hold out Programmable Logic Arrays (PLAs) be built without relying on lithography to conventionalism their smallest features? In this paper, we detail designs which exploit emerging, bottom-up square synthesis techniques to patterned advance to PLAs using molecular-scale nanowires. Our new designs accommodate technologies where the solitary(prenominal) post-fabrication programmable element is a non-restoring diode. We let on stochastic techniques which allow us to restore the diode formation of system of logic at the nanoscale so that it can be cascaded and interconnected for general logic evaluation. Under right assumptions using 10nm nanowi res and 90nm lithographic support, we project yielded logic density rough 500,000nm2 /or experimental condition for a 60 or-term array; a complete 60-term, two-level PLA is some the same size as a unmatchableness 4-LUT logic block in 22nm lithography. Each or term is comparable to(predicate) in area to a 4-transistor hardwired provide at 22nm.

social occasion sample datapaths and conventional programmable logic benchmarks, we work out that to each one 60-or-term PLA plane will provide equivalent logic to 510 4-input LUTs. mwilson@caltech.edu not make sense to develop PLAs; logic was customized by discre te wiring (e.g. patch cables). in one case l! ithography could support enough logic on a single chip to accommodate programmable con?guration elements, it became interesting and utilitarian to accept memory elements which could con?gure the state of the device. As a way out we developed PALs, PLDs, and ultimately FPGAs. Now it is adequate possible to intent beyond lithography and explore how we can build devices without relying on lithography to pattern our smallest feature sizes.
