Abstract
Simulated annealing (SA) was successfully implemented and accelerated by in-memory computing hardware/software package using RRAM crossbar arrays to solve a spin glass problem. Ta2O5-based RRAM array and stochastic Cu-based CBRAM devices were utilized for calculation of the Hamiltonian and decision of spin-flip events, respectively. A parallel spin-flip strategy was demonstrated to further accelerate the SA algorithm.
