  • Enhanced binary content addressable memory for longest prefix address matching
    Patent number: 6266262
    Abstract: A modified binary content addressable memory (CAM) (700) having a fast variable prefix matching capability is disclosed. The modified CAM (700) includes modified CAM cells (702(0,0) to 702(n,m)), each of which includes a store/compare circuit (704(0,0) to 704(n,m)) for storing a data value and comparing the data value to a comparand value. In addition, each modified CAM cell (702(0,0) to 702(n,m)) further includes a multiplexer (MUX) circuit (706(0,0) to 706(n,m)). Each MUX circuit (706(0,0) to 706(n,m)) receives a non-shifted comparand value from a modified CAM cell of a previous row and same column, and a shifted comparand value from a modified CAM cell of the previous row and an adjacent column. The MUX circuits (706(0,0) to 706(n,m)) enable a comparand value to be shifted as it is applied to consecutive data values.
