N2 - 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 (STT-MTJ) is used as NV memory element in magnetic full adder (MFA). The proposed approximate MFAs are implemented with 28nm ultra thin body and buried oxide (UTBB) fully depleted silicon-on-insulator (FD-SOI) technology. Simulation results are presented including power consumption, circuit latency, leakage power, error distance and reliability performance. Low Vdd design strategies are discussed as well.
