ABSTRACT:
A fully associative CAM that removes the need for a strobe and improves the overall performance of the CAM. The inventive CAM takes advantage of the fact that only one entry, if any, of the CAM will match the applied address. If a CAM entry matches the applied address, then it can be assumed that the address did not match the other CAM entries. Therefore, to access a certain entry in the memory array, it can be determined that the match lines of the CAM entries not corresponding to this certain matching entry in memory have each left the precharged state. By using the other state information, the proper memory bits can be selected without the use of a strobe.
