As the technology scales down, the increased power density brings in significant system reliability issues. Therefore, the temperature monitoring and the induced power management become more and more critical. The thermal fluctuation effects of the recently discovered spintronic memristor make it a promising candidate as a temperature sensing device. In this paper, we carefully analyzed the thermal...
Spin-transfer torque random access memory (STT-RAM) is a promising nonvolatile memory technology aiming on-chip or embedded applications. In recent years, many researches have been conducted to improve the storage density and enhance the scalability of STT-RAM, such as reducing the write current and switching time of magnetic tunneling junction (MTJ) devices. In parallel with these efforts, the continuous...
Spin-transfer induced magnetization switching in a MgO-based magnetic tunneling junction (MTJ) has been measured over a wide time range. It was found that the switching current response is asymmetric going from the high resistance state to the low resistance state and vice versa. This asymmetry must be taken into consideration to optimize the read-write margin for a 1T1R (single transistor, single...
Thermal-assisted spin-transfer torque random access memory (STT-RAM) has been considered as a promising candidate of next-generation nonvolatile memory technology. We conducted finite element simulation on thermal dynamics in the programming process of thermal-assisted STT-RAM. Special attentions have been paid to the scalability and design space of the thermal-assist programming scheme by varying...
