我们提出并实验证明随机计算（SC）与一个单一的磁性隧道结（MJT），利用设备的物理特性和行为。脉冲幅度、偏置场、偏置电流和脉冲宽度用作输入;输出是开关概率。单个MJT可以实现加法和乘法运算。该方案受益于由自旋转移矩（STT）或其他未来开关机制操作的MTJ的高能量效率。随机操作自然地提供高容错性、低复杂性和低面积成本。
We propose and experimentally demonstrate stochastic computing (SC) with a single magnetic tunnel junction (MJT), exploiting the physical properties and behaviors of the device. Pulse amplitude, bias field, bias current, and pulse width are used as inputs; the output is the switching probability. A single MJT can implement the operations of addition and multiplication. The scheme benefits from the high energy efficiency of an MTJ operated by spintransfer torque (STT), or other future switching mechanisms. Stochastic operations naturally provide high error tolerance, low complexity and low area cost.
