Abstract
A method, system, and apparatus for making all content addressable memory words available for comparison in a data compressor is provided. In one embodiment, new data, to be compared with old data, is launched into a master. The new data from the master latch is launched into a slave latch and compare logic for each of a plurality of content addressable memory words within a content addressable memory (CAM). After the comparison has been made between the new data and the old data contained within the CAM word, the new data from the slave latch is written into the one of the plurality of content addressable memory words. Thus, each CAM word, including the CAM word that will be overwritten by the new data, is available for comparison to the new data.
