ABSTRACT:
Associative retrieval of data via the technique of superimposed code words is accomplished by circuitry which automatically generates the codes, and which searches through stored code words to find the ones that match a given query code. Code generation is performed using pseudo-random techniques that are reproducible, obviating the need for a pre-prepared code dictionary. Identification of the codes that meet a match requirement is accomplished by logically AND'ing selected bits from the stored codes, said selection being determined by the query code.
