Abstract
In order to provide a more efficient method and system for data lookups, it is proposed to provide the known CAM (100) with an additional comparator (301). The comparator (301) does not comprise a memory circuit and therefore allows a faster comparison of input data (D0 to D31) with compare data (C0 to C31) than the known compare circuit (106). In addition, it is proposed to temporarily inhibit forwarding of the output signal of the specific CAM circuit into which the input data (D0 to D31) are written, in order to avoid forwarding of a wrong match signal to the data processing system.
