Abstract

This paper introduces a novel design of reconfigurable Spintronic Threshold Logic Gate (STLG), which employs spintronic weight devices to perform current mode weighted summation of binary inputs, whereas, the low voltage spintronic threshold device carries out the thresholding operation in an energy efficient manner. The proposed STLG can operate at a small terminal voltage of ∼50mV, resulting in ultra-low energy consumption. The device-circuit simulation results for common benchmarks show that the proposed STLG circuit can achieve 87.5% and 11.1% energy reduction compared with state-of-the-art CMOS look-up-table (LUT) and Memristive Threshold Logic Gate (MTLG) respectively. The ultra-low programming energy of spintronic weight device also leads to three orders lower reconfiguration energy of STLG compared with MTLG design.
