摘要:
A method and apparatus are provided for implementing power saving in a content addressable memory (CAM). A compare array is matched against a key and if a match occurs then logic coupled to the compare array generates a hit signal. A data array includes precharge circuitry and data output latches to capture the data output. A clock gate coupled to the logic provides clock signals to the output latches and precharge circuitry of the data array when a hit occurs. When a hit does not occur, the clock signals are gated off to the output latches and precharge circuitry of the data array.
