Abstract
A circuit (11) for use in an associative memory device, one such circuit being associated with each word location in memory, for indicating a match when the word associated with a given circuit (11) is a match for a current portion of a search pattern and the previous word is a match for a previous portion of the search pattern. In operation of the circuit (11), a latch (23) is initialized to a match condition, and provides a match output, which is also applied to the next successive circuit, for the next successive word in memory. The latch (23) is controlled by an AND gate (21), to which is applied the output signal from the circuit for the previous word in memory and a signal indicating a match or non-match for the word in memory associated with circuit (11) containing AND gate (21).
