Ramsauer et al. proved in 2020 that single-head attention in a Transformer is mathematically equivalent to one retrieval update of a modern Hopfield network: the query corresponds to the current state, the keys correspond to the stored patterns, and the attention weights correspond to the retrieval distribution.
