Abstract

A method and device are disclosed for an associative and approximate, analog or digital scanning of databases that allows for the asynchronous accessing of data from a mass storage medium. The invention includes circuitry and decisi on logic at the mass storage medium level for determining a key identifying the data of interest, continuously comparing the key to a signal generated from a reading of the data from the mass storage medium with an approximate or exac t matching circuit to determine a pattern match, determining a correlation val ue between the key and the data as it is read in a continuous fashion, and determining a match based upon a preselected threshold value for the correlation value. The key and data may be either analog or digital.
