AB  - ContentAddressable Memory (CAM) is a specialmemory used in search engines for numerous applications, especially in networkrouters for packet forwarding. The CAMoperation begins with pre-charging followed by evaluating the match-lines (MLs)for searching the data in the stored memory. CAM stores unique words in theirarray of cells such that only one word ismatched for a given search word. ML associated with matched word retainsits state and the remaining MLs drain their charge. Ternary content addressablememory (TCAM) is a fast lookup hardware device used for high-speed packetforwarding. However, significant powerconsumption and high cost limits its versatility and popularity. In this paper,a design has been made for TCAMarchitecture with pre-charge controller. The pre-charge controller helps inpredicting the mismatched MLs during pre-charge phase. This prediction happensat an early stage and helps in terminating the pre-charging of the line. This assures the design of TCAM which consumes lowpower and also improves the performance. The proposed early predict8 × 8 TCAM architecture simulations wereperformed in 45nm technology node using Cadence Virtuoso. The proposed TCAMdesign exhibits 16.6% reduction in power, 24.7% decrement in delay and 37.1%minimization in energy metric than basic TCAM NOR.
