Ternary Content-Addressable Memory (TCAM) is often used in high speed search intensive applications such as ATM switch, IP filters. Hence, currently ZTCAM, is introduced which emulates the TCAM functionality with SRAM. It has some drawbacks such as low scalability, low storage density, slow access time and high cost. But, this paper proposes novel memory architecture of existing Z-TCAM, but with STTRAM instead of SRAM. Hence the area, delay and power by using lower power consumption Spin Transfer Torque RAM (STT RAM) instead of SRAM.
