A content addressable memory (CAM) device having circuitry to generate a biased
sequence of addresses. A first counter circuit increments an address value in response
to a clock signal and resets the address value to a start address in response to
a control signal. A second counter increments a limit value in response to a control
signal. A compare circuit compares the address value and the limit value and, if
the address value and the limit value have a predetermined relationship, asserts
the control signal.
