The present invention relates to methods and systems for storing and querying database entries with neuromorphic computers. The system is comprised of a plurality of encoding subsystems (1) that convert database entries and search keys into vector representations, a plurality of associative memory subsystems (3) that match vector representations of search keys to vector representations of database entries using spike-based comparison operations, a plurality of binding subsystems (8) that update retrieved vector representations during the execution of hierarchical queries, a plurality of unbinding subsystems (9) that extract information from retrieved vector representations, a plurality of cleanup subsystems (10) that remove noise from these retrieved representations, and one or more input search key representations that propagates spiking activity through the associative memory (3), binding (8), unbinding (9), cleanup (10), and readout subsystems to retrieve database entries matching the search key.
