Probabilistic-Bits based on Ferroelectric Field-Effect Transistors for Probabilistic Computing

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