a A digital content-addressable memory (CAM) compares the input word against all stored words or rows in parallel. Ternary CAM (TCAM) is an extension where in addition to search/stored “0” and “1” values, “X” is a wildcard that always yields a match. Data are searched along vertical Data Lines (DL) and the binary match result of the compare operation between searched and stored words in each row is sensed on horizontal Match Lines (ML). The CAM returns the match location of stored data and the searched input (first row here). b The analog CAM searches and stores analog data, where the input data can be a continuous value, and the stored data are a continuous interval with a lower and upper bound representing an acceptance range for a match.
