- Abstract
- Stochastic computing with probabilistic bit streams is a useful computing method due to its advantage of a higher degree of error tolerance than the conventional binary system. To achieve computational efficiency, electronic devices with an inherent stochastic nature have been explored for integration into a stochastic computing system. In this paper, we demonstrate probabilistic bit streams obtained from the telegraphic switching of a two-input magnetic tunnel junction (MTJ). Extension of the input configuration provides an advantage in architectural comparability for applying to a practical computing circuit. We also show that an MTJ can be a generic stochastic device, whose output directly constructs bit streams representing the probabilistic weight according to two independent progammable inputs, namely, the applied magnetic field and the current.
