PARALLEL ASSOCIATIVE MEMORY ABSTRACT A parallel associative memory provides a way of recognizing or identifying observed data patterns. Each of a plurality of memories stores a plurality of recognition patterns. In response to receipt of a recall pattern to be identified, the recall pattern is contemporaneously compared to the recognition patterns stored in the memories and an exact or best match recognition pattern is selected. In a preferred embodiment, the memories may store multiple data bases each of which includes patterns having different lengths and different radii of attraction. The comparison process is controlled by masks which specify respective portions of the patterns which may include the radii of attraction, bits which must identically match, bits which are ignored, bits which are compared in a bit-wise fashion, and bytes which are compared by multiplication. A correlation is computed and selectively adjusted by the respective radii of attraction. A specified number of the patterns having the best correlation are identified, subject to selected threshold conditions, and sorted according to their respective correlations. The parallel nature of the memory lends itself to a hierarchical organization for increased storage capacity and to parallel processing which increases the speed of the identification or recognition process and thereby allows a broad range of applications. These applications includes fast retrieval of exact or inexact data, diagnosis, image processing and speech recognition.
