Abstract: An associative store, particularly designed for performance of logic by table-look-up, has fixed search and read fields. Input to the search field is through an encoder which converts sets of plural binary inputs into one out of K set of drive signals, where K is an integer related to the number of bits in each set. Output signals from the read field are decoded by exclusive-ors corresponding ordered bit positions of two read arrays. The search field is either conventionally addressed for loading or read-only.
