有某些类别的电阻器、电容器和电感器，当受到适当频率的周期性输入时，在其特性响应中产生磁滞回线。在这里，我们表明，这种存储元件的滞后也可以引起适当强度的白色噪声，即使在非常低的频率的外部驱动场。我们说明了这种现象，使用的存储电阻器的物理模型，实现由TiO（2）薄膜夹在金属电极之间，并讨论在何种条件下，这种效果可以观察到实验。我们还讨论了它的影响，现有的记忆系统中描述的文献和有色噪声的作用。
There are certain classes of resistors, capacitors, and inductors that, when subject to a periodic input of appropriate frequency, develop hysteresis loops in their characteristic response. Here we show that the hysteresis of such memory elements can also be induced by white noise of appropriate intensity even at very low frequencies of the external driving field. We illustrate this phenomenon using a physical model of memory resistor realized by TiO(2) thin films sandwiched between metallic electrodes and discuss under which conditions this effect can be observed experimentally. We also discuss its implications on existing memory systems described in the literature and the role of colored noise.
