摘要： A search unit including a distributor TCAM and a DRAM search unit and a method to divide a database of TCAM rules is disclosed. The method includes selecting a rule having multiple “don't care” values and selecting a bit of the rule having a “don't care” value, generating two distributor rules based on the selected rule, associating rules of the database which match each of the distributor rules with the distributor rule they match to create subset databases, and repeating the steps of selecting, generating and associating until the average number of rules in each subset database is at or below a predefined amount. A DRAM storage unit has a section for each subset database, where each section is pointed to by a different distributor rule. A DRAM search unit matches an input key to one of the rules in the section pointed to by the matched distributor rule.

摘要： A content addressable memory (CAM) unit does not have any in-cell comparator circuitry. The CAM unit includes a memory array, a multiple row decoder, a controller and an output unit. The memory array has storage cells arranged as data rows and complement rows. The multiple row decoder activates more than one row of the memory array at a time and the controller indicates to the multiple row decoder to activate data rows or complement rows as a function of an input pattern to be matched. The output unit indicates which columns generated a signal, the columns matching the pattern.
