Extended Data Fig. 1: Revised ASIC PIM experimental results.
Frequency plot for the end state of experimental factorization attempts of the 24-bit semiprime 12,441,691 on the second ASIC which utilized the modified p-bit mapping. For readability, both orderings of each factor pair are treated as a single data point, of which the correct solution pair of 3119 and 3989 appears in a plurality of trials. A CMOS-based random number generator integrated within the PIM design area was used to generate the necessary pseudo-random numbers. The temperature was kept constant at a value of 4, over the approximately 0.8 s of convergence during each trial.
