Abstract:
A programmable priority encoder is disclosed for use with the device such as a Content Addressable Memory (CAM) device having a plurality of array objects to be encoded in binary and arranged in row and columns. Match lines are adapted to be connected to a plurality of arrayed objects associated with respective rows. A plurality of encoder cells, each having a memory element and forming an encoder block are arranged in rows. Precharged bus lines are operative with the encoder cells and match lines. The precharged bus lines are discharged indicating a match and priority is assigned to rows based on logic values stored within the memory elements of the encoder cell.
