Programmable Resistive-Switch Nanowire Transistor Logic Circuits

Abstract

Programmable logic arrays (PLA) constitute a promising architecture for developing increasingly complex and functional circuits through nanocomputers from nanoscale building blocks. Here we report a novel one-dimensional PLA element that incorporates resistive switch gate structures on a semiconductor nanowire and show that multiple elements can be integrated to realize functional PLAs. In our PLA element, the gate coupling to the nanowire transistor can be modulated by the memory state of the resistive switch to yield programmable active (transistor) or inactive (resistor) states within a welldefined logic window. Multiple PLA nanowire elements were integrated and programmed to yield a working 2-to-4 demultiplexer with long-term retention. The well-defined, controllable logic window and long-term retention of our new one-dimensional PLA element provide a promising route for building increasingly complex circuits with nanoscale building blocks.

Recommended Methods to Study Resistive Switching Devices

“…RS‐based electronic products can include different amounts of RS cells depending on their applications, ranging from few (<10) in detectors and logic gates, to billions in nonvolatile memories (NVM) and artificial neural networks . The main challenges in the fabrication of RS‐based NVMs are to ensure that all devices show good performance (see Table 1 ), and that all the RS cells within the RS device show nearly identical RS behaviors (i.e., low cell‐to‐cell variability).…”

Hybrid Flexible Resistive Random Access Memory‐Gated Transistor for Novel Nonvolatile Data Storage

“…[ 16 ] Therefore, hybrid structures to integrate RRAM with active circuit elements such as transistors in which the RRAM array is used for peripheral routing for programmable architecture were proposed. [16][17][18][19] Hybrid circuits are expected to deliver the enhanced functionality especially for saving both the operating power and chip area. In another aspect, efforts should made to search for programmable logic elements with bistable functions.…”

Advances in nanowire bioelectronics

“…Over past two decades, substantial advances in the 'bottomup' synthesis of 1D semiconductor nanowires have enabled precise control of the size, morphology, and chemical composition of these building blocks, thereby enabling many novel nano devices, including nanowire logic circuits [21,24,52,53], memories [54], photodetectors [55,56], photovoltaic solar cells [23,57], light-emitting diodes [58], lasers [20,36] and chemical-biological sensors [18,59]. Moreover, the bottomup paradigm allows for the integration of nanowire devices in non-conventional, heat-sensitive and highly-flexible materials for new applications beyond the capability of current CMOS technology.…”
