Field programmable gate array (FPGA) is widely used in the acceleration of deep learning applications because its reconfigurability, flexibility, and fast time-to-market. However, conventional FPGA suffers from trade-off between chip area reconfiguration latency, making efficient accelerations that require switching multiple configurations still elusive. Here, we propose a ferroelectric field-effect transistor (FeFET)–based context-switching supporting dynamic to break this trade-off,...
Abstract Existing circuit camouflaging techniques to prevent reverse engineering increase circuit-complexity with significant area, energy, and delay penalty. In this paper, we propose an efficient hardware encryption technique minimal complexity overheads based on ferroelectric field-effect transistor (FeFET) active interconnects. By utilizing the threshold voltage programmability of FeFETs, run-time reconfigurable inverter-buffer logic, two FeFETs inverter, is enabled. Judicious placement...
Since the discovery of CMOS-compatible and highly scalable ferroelectric HfO2, there has been a significant revival interest in developing devices for high performance energy-efficient embedded nonvolatile memories. Multiple memory are under investigation by harnessing polarization states. These include FET (FeFET), capacitor based random access (FeRAM), tunnel junction (FTJ). Though underlying storage mechanisms same these devices, their sensing different. This difference leads to...
Logic camouflage is a widely adopted technique that mitigates the threat of intellectual property (IP) piracy and overproduction in integrated circuit (IC) supply chain. Camouflaged logic achieves functional obfuscation through physical-level ambiguity post-manufacturing programmability. However, discussions on programmability are confined to level cells/gates, limiting broader-scale application camouflage. In this work, we propose novel module-level configuration methodology for...
Intellectual property (IP) piracy has become a non-negligible problem as the integrated circuit (IC) production supply chain is becoming increasingly globalized and separated that enables attacks by potentially untrusted attackers. Logic locking widely adopted method to lock module with key prevent hackers from cracking it. The critical aspect of logic locking, but existing works have overlooked three possible challenges key: safety storage, easy key-attempt interface key-related overheads,...
Field Programmable Gate Array (FPGA) is widely used in acceleration of deep learning applications because its reconfigurability, flexibility, and fast time-to-market. However, conventional FPGA suffers from the tradeoff between chip area reconfiguration latency, making efficient accelerations that require switching multiple configurations still elusive. In this paper, we perform technology-circuit-architecture co-design to break with no additional cost lower power consumption compared...
