India, Sept. 16 -- Researchers from CEA-Leti and Spintec in Grenoble, and from C2N/Universite Paris-Saclay, have demonstrated a hybrid nanoelectronic Ising machine that combines hafnium-oxide memristors with stochastic magnetic tunnel junctions (SMTJs) to solve hard combinatorial optimization problems.

Reported in Nature Communications, the article, "Intrinsic Annealing in a Hybrid Memristor-Magnetic Tunnel Junction Ising Machine," introduces an intrinsic annealing mechanism that could pave the way for more compact, faster, and energy-efficient hardware accelerators.

Ising machines are specialized hardware accelerators designed to search for optimal solutions among vast numbers of possibilities. They operate by repeatedly updating binar...
