Claim 8:
9. An apparatus comprising:
a ternary content addressable memory (TCAM) comprising:
a first plurality of rows of memory cells configured to store a plurality of respective data inputs;
a second plurality of rows of memory cells configured to store a plurality of respective masks; and
first and second buses; and

control circuitry configured to:
generate a first control signal configured to write a data input in a row of the first plurality of rows of memory cells using the first bus in a first clock cycle,
generate a second control signal configured to write a mask in a row of the second plurality of rows of memory cells using the second bus in the first clock cycle, wherein the control circuitry is configured to generate the first control signal in response to an edge of the second control signal, and
use the first bus or the second bus to mask one or more columns of the TCAM during a search operation.
