Defect-tolerant N2-transistor structure for reliable nanoelectronic designs

Defect-tolerant n2-transistor structure for reliable nanoelectronic designs

Nanodevices based circuit design will be based on the acceptance that a high percentage of devices in the design will be defective. In this work, we investigate a defect tolerant technique that adds redundancy at the transistor level and provides built-in immunity to permanent defects (stuck-open, stuck-short and bridges). The proposed technique is based on replacing each transistor by N-transi...

Defect-Tolerant Interconnect to Nanoelectronic Circuits: Internally-Redundant Demultiplexers Based on Error-Correcting Codes

We describe a family of defect-tolerant demultiplexers based on error-correcting codes. A conventional demultiplexer with a k-bit input address and 2-bit output may be fortified against certain defect types by widening its address bus to n > k bits to permit an encoded address to be used within the demultiplexer. The redundant address is computed by an encoder that guarantees a minimum Hamming ...

Intrusion-Tolerant Reliable Broadcast

We consider a system with n processes where some of them can show a byzantine behavior. A byzantine process can deviate arbitrarily from the protocol, e.g., dropping messages, changing the content of a message (different recipients may receive different content of the same broadcast message), delivering messages not sent by any process or creating fake messages. This paper introduces a new broa...
