摘要

In this paper, a reordered search mechanism is introduced for high-speed low-power content-addressable memories (CAMs). Only by searching a few bits of a search word the mismatches can be occured. So to reduce the power consumption, search word circuit is partitioned into two sections that are searched sequentially. Searching will be faster if the last few bits is compared other than the rest of the bits. Each word circuit has a local control signal which controls the circuit. This allows the circuits to be operated in the required phase which greatly reduces the cycle time.
