An apparatus and method for generating a comparand in a content addressable memory array. The apparatus includes a content addressable memory (CAM) array and translation circuitry to receive translation information indicative of translation of a bit group from an initial position in input data to a different position in a comparand transmitted to the CAM array. The translation circuitry includes a switch circuit, one or more storage elements to store the translation information, and one or more decode circuitry to decode the translation information and establish switch circuit connections between the initial position and the position in the comparand. The apparatus also includes program circuitry to provide a bit level programming interface with the translation circuitry. The apparatus may also include a programming bit register to store programming information in the form of a binary pattern where each bit represents a bit group of the input data.
