In this paper, we propose efficient scalable nonvolatile flip-flops (NV-FF) with single-stage pulsed latch which is explored as the flip-flop core in hybrid CMOS/MTJ (magnetic tunnel junction) integration. Typical full-custom FF cores are implemented with a 28nm ultra-thin body and buried oxide (UTBB) fully depleted silicon-on-insulator (FD-SOI) technology. The performance analysis takes into account...
Approximate computing and its related topics have shown the potential in next generation computing systems. In this paper, new circuit level design for approximate computing is proposed based on non-volatile (NV) logic-in-memory structure. Two types of NV approximate adders are implemented with circuit reconfiguration and insufficient writing current. Spin torque transfer magnetic tunnel junction...
Random numbers are widely used in the cryptography and security systems. However, most of the true random number generators (TRNG) which use physical randomness are with high complexity and high power consumption. This paper proposes a new TRNG circuit using magnetic tunnel junction (MTJ). As one of the reliability issues in MTJ based circuit, the stochastic switching behavior provides a perfect physical...
Stochastic Computing (SC) with random bit streams has been used to replace binary radix encoding. SC-based logic cicuits take advantage of area minimization, fast and accurate operation and inherent fault tolerance. In this paper, the stochastic characteristics inherent in Spin Torque Transfer Magnetic Tunnel Junction (STT-MTJ) bring on an innovative stochastic number generator (SNM) circuit. The...
