1
Nano-Array Hybrid CMOS/Nanoelectronic Circuits e. g. CMOS, FPNI
2
CMOL, FPNI, Nano-Array Realism –We were charged to find a magic solution that would continue scaling in power and speed, given that density scaling looks healthy –CMOL and FPNI continue scaling in density but are not a magic solution for power and speed –Could provide for progress while reinforcing realistic expectations Risk Reduction/Infrastructure/Horizontal Solution –Circuit works with 4 devices presented at this meeting, and others too
3
Technical Advantages Enables features smaller than lithographic resolution from a manufacturing process that is not as technically challenging as lithography –Drawing parallel lines or nano-imprint Stacks on top of CMOS thus enabling additional function without taking away real estate for CMOS (2½-D) Can be used to create diverse structures –(non-volatile) memory –Logic (FPGA-like)
4
Possible Advantage over CMOS CMOS, FPNI will not beat the fundamental limits on CMOS logic However, CMOS performance includes a major effect due to wire CMOL, FPNI alter the CMOS performance equation at the wire level and could offer a modest boost “Beyond CMOS” –Addressed by Andre’s analysis that benefit was partly due to lots of devices and partly due to reduced linewidth
5
Roadmap Advocates prepared a roadmap –We can debate the realism of the the advocates’ roadmaps, but the mere presence of a roadmap is a sign of considerable maturity Speed, power and density offer some advantage over plain CMOS
6
Design Tools already exist for design with CMOL, FPNI, etc. –We can debate the maturity of the tools, but the mere presence of tools is a sign of considerable maturity
7
Logic Family FIT rates estimated Defect tolerance included Power estimates, including wire delay
8
Possible Secondary Benefits Andre showed head-to- head competition with CMOS/ASIC – looked like a good competition. What might come beyond competing with CMOS? Advantages that could come from crosspoint device –non-volitile memory, which would introduce new function –RAD/SEU hard, which would be an advance “Design modality choice” – designer could optimize across design by ASIC, nano-array, or a mixture or design styles
