Abstract
A CAM device (100) according to an embodiment can include a control circuit (106) that can sequentially activate, with dummy operations, an increasingly larger number of CAM blocks (102-1 to 102-16) in response to a start-up circuit (104) indication until an initial number of CAM blocks is activated. A control circuit (106) can receive a user configurable block number (USER_BLK) and adjust the number of CAM blocks in a sequentially fashion, with dummy operations, until the user configurable number of CAM blocks is being activated. If a received command is targeted to less than the user configurable block number of CAM blocks, a control circuit (106) can activate, with dummy operations, an additional number of CAM blocks so that the total number of CAM blocks activate equals the user configurable block number.
