    摘要： A conductive write line of a memory device includes a resistive heating portion for setting and resetting a phase-change material (PCM) storage cell of the device. A dielectric interface extends between the resistive heating portion of the write line and a side of the storage cell, and provides electrical insulation while allowing for thermal coupling between the resistive heating portion and the storage cell. A width of the resistive heating portion of the write line may be less than a width of the storage cell and/or may be less than a width of adjacent portions of the write line, between which the resistive heating portion extends. The side of the storage cell may define a channel of the storage cell through which the write line passes, such that the resistive heating portion is located within the channel.

    摘要： Embodiments of systems and methods for improved measurement of transient thermal responses in electronic systems are described herein. Embodiments of the disclosure use the known thermal transfer function of an electronic system to generate an equivalent resistor-capacitor (RC) network having a dynamic response that is identical to a given power excitation as the actual electronic system would have to that power excitation. Using the analogy between thermal and electrical systems, a Foster RC network is constructed, comprising a plurality of RC stages in which resistors and capacitors are connected in parallel. Subsequently, the analog thermal RC network is converted into an infinite impulse response (IIR) digital filter, whose coefficients can be obtained the Z-transform of the analog thermal RC network. This IIR digital filter establishes the recursive relationship between temperature output at the current time step and measured power input at the previous time step. Using this IIR digital filter, temperature response subject to arbitrary time-dependent power can be calculated in very small amount of time compared with prior art methods.
