Abstract :
An embedded ternary CAM macro derived from a 9M stand alone part with die size of 148 mm2 uses a novel 3.542 μm2 SRAM half-cell on a standard 0.13 μm logic process. In the embedded form it takes 13 mm2/Mbit. The macro achieves 166 M-searches/s with low power, under 0.5 W/Mbit. A divided match line greatly reduces the power inherent in parallel searches. Prioritized multiple match output, status bit functions, and on-the-fly variable word width are included.
