Abstract(in English) | One of the leakage reduction techniques is nonvolatile power gating(NVPG) by using magnetic tunnel junction(MTJ). In the NVPG, volatile circuits such as a flip-flop are made nonvolatile by applying the MTJ, so solving the problem of losing data due to power off of the PG. However, when the power supply voltage for nonvolatile flip-flop (NVFF) is lowered gradually, writing to MTJ and reading from MTJ (nonvolatile operation) do not work properly. Although we have to choose the power supply voltage of NVFF within the limit of working nonvolatile operation properly, we want to make logic circuits including the FF operate at a low voltage for power consumption. In this paper, in order to enable normal operation in NVFF at lower voltage, we propose NVFF circuit using two power supplies. |
