This work proposes a memristance decoder circuit with self-temperature calibration. Its main building block is a comparator which is based on current mode circuit to achieve high performance at low power. The VTEAM model is modified to include the temperature effect on the memristance in the analysis. The simulation results show the comparator's characteristics: 1.70% maximum offset, 2.91ns worst-case latency, 343MHz maximum frequency and 48.79fJ maximum energy per comparison. The proposed memristor model reveals that memristance at high resistive state degrades quadratically with the rise of the temperature and at 85C nearly reaches the memristance of low resistive state.
