Abstract

Words of data are maintained in content-addressable memory cells arranged in rows. Two of the rows are timing reference rows, and the remainder of the rows are data rows that maintain the words of data. The data rows form individual matchlines. A first of the reference rows forms a precharge reference matchline, and a second of the reference rows forms an evaluation reference matchline. The timing for the individual matchlines to precharge is based on the time to precharge the precharge reference matchline, and timing for the individual matchlines to evaluate a search word is based on the time for the evaluation reference matchline to evaluate the search word.
