Abstract:
A content addressable memory (CAM) suppresses an indication of a match in response to determining that the entry that stores data matching received compare data is the subject of a write operation. To suppress the indication, an address decoder decodes a write address associated with the write operation to determine the entry of the CAM that is the subject of the write operation, and provides control signaling indicative of the determined entry. The CAM uses the control signaling to suppress any match indications for the entry being written, thereby preventing erroneous match indications.
