摘要
A probabilistic bit (p-bit) is the fundamental building block in the circuit of probabilistic computing (PC), and it produces a random binary bitstream with tunable probability. Utilizing the randomness induced by thermal noise-induced lattice vibration in the ferroelectric (FE) material, we propose the p-bits based on stochastic ferroelectric FET (FeFET). The domain dynamic is revealed to play crucial roles in FE p-bits' stochasticity, as the domain coupling suppresses the dipole fluctuation. The proposed FE p-bits possess the advantages of both extremely low hardware cost and scalability for p-bit circuitry, rendering it a promising candidate for PC.
