N2 - 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 hybrid MOS-MTJ process allows to design a 4T1M structure SNM with 1.98μm1.46μm layout area, using 28 nm ultra thin body and buried oxide fully depleted silicon-on-insulator (UTBB FD-SOI) technology. A case study of designed SNM is performed by polynomial function synthesis, which significantly reduces area. The proposed circuit also takes advantage of non-volatility and infinite endurance from STT-MTJs, which can be applied to reliability-aware circuits and systems1.
