Abstract

An associative memory comprises an array of memory cells arranged in rows and columns, each row comprising a plurality of segments each of which comprises a set of said memory cells, wherein each memory cell has compare circuitry for comparing input data with data stored therein and for generating a cell match signal when said input data matches said stored data and match signal combining circuitry for receiving a match signal from a preceding cell in the set and operable to generate a logical value dependent on the match signal of the current cell and the match signal of the preceding cell whereby each segment generates a resultant segment logical value, the memory further comprising combinatorial logic circuitry associated with each row for combining said resultant segment logical values to generate a final output match signal for that row.
