Performance simulation and analysis of a CMOS/nano hybrid nanoprocessor system

Abstract

This paper provides detailed simulation results and analysis of the prospective performance of hybrid CMOS/nanoelectronic processor systems based upon the field-programmable nanowire interconnect (FPNI) architecture. To evaluate this architecture, a complete design was developed for an FPNI implementation using 90 nm CMOS with 15 nm wide nanowire interconnects. Detailed simulations of this design illustrate that critical design choices and tradeoffs exist beyond those specified by the architecture. This includes the selection of the types of junction nanodevices, as well as the implementation of low-level circuits. In particular, the simulation results presented here show that only nanodevices with an 'on/off' current ratio of 200 or more are suitable to produce correct system-level behaviour. Furthermore, the design of the CMOS logic gates in the FPNI system must be customized to accommodate the resistances of both 'on'-state and 'off'-state nanodevices. Using these customized designs together with models of suitable nanodevices, additional simulations demonstrate that, relative to conventional 90 nm CMOS FPGA systems, performance gains can be obtained of up to 70% greater speed or up to a ninefold reduction in energy consumption.

Solid-state electron transport in Mn-, Co-, holo-, and Cu-ferritins: Force-induced modulation is inversely linked to the protein conductivity

“…This capacity of pressure-tuning of the electronic band gaps of the ferritins, in general, could be useful in realization of ferritin-based bioelectronic devices of sandwich configuration where certain degrees of compressive force may need to be applied on the intermediate protein layer for controlling the device function [19,20]. It is important to note here that by using metal core reconstituted ferritins, junctions of high conductivity (''on'') and low conductivity (''off'') states with a variety of combinations may be envisaged [21][22][23][24].…”

Tuning Band Gap of Holoferritin by Metal Core Reconstitution with Cu, Co, and Mn

“…Fifth, the metal center of ferritin can be substituted with other metals like manganese, cobalt, copper, palladium, gold, and so forth with negligible change in its geometric structure. − Since the apo form of ferritin consists of the same polypeptide shell with an empty cavity (7–8 nm) inside the protein shell, in this study it has been tested whether insertion of different metals of a wide range of conductivity within the ferritin nanocavity could result in distinct changes in the ferritin band gap. It may not be too high an expectation that, if successful, these metal core reconstituted ferritin systems may serve as the basis for configurable nanoscale bioelectronic devices where a junction of a high-conductivity ('on’) state and a low-conductivity (‘off’) state with different combinations − is required.…”

Electroforming and Resistance Switching Characteristics of Silver-Doped MSQ With Inert Electrodes

“…Due to their simple two-terminal structure, new high integration density architectures can be employed, like crossbar arrays [10]. Crossbar arrays consume an area of only 4 F 2 [1], F being the minimum obtainable feature size, making them ideal candidates for memory applications [11], [12], for reprogrammable interconnects [13], [14], and defect-tolerant logic networks [15].…”
