Abstract :
A 4.5 Mb dynamic ternary CAM (DTCAM) is designed in 0.13 μm embedded DRAM technology. A performance of 143 M searches/sec is achieved at a power dissipation of 1.1 W and on a small silicon area of 32 mm2. A 3.6-times yield improvement is estimated by employing pipelined hierarchical searching and row/column-shift redundancy.
