Abstract
A CAM device including a CAM array, multiple match resolution (MMR) circuitry, and a priority encoder allows the addresses of multiple matching locations resulting from a first search operation to be generated without losing the match results generated in second search operation initiated prior to detection of the multiple match condition for the first search operation. When the multiple match condition is detected, the MMR circuitry asserts a stall signal that stalls search operations in the CAM array. The asserted stall signal also causes the match results of the first and second search operations to be stored in separate memory elements so that the addresses of all matching locations for the first search operation can be generated without disturbing the match results of the second search operation.
