ResearchIndex Home McAuley, A., Tsuchiya, P., and Wilson, D. Fast multilevel hierarchical routing table using contentaddressable memory . U.S. Patent Serial Number 034444, 1995. Some CAMs allow a mask of bits that must be matched. Although there are expensive so called ternary CAMs available allowing a mask to be specified per word, the mask must typically be specified in advance. Large CAMs are usually slower and much more expensive than ordinary memory.
Typical CAMs are small, both in the number of bits per entry and the number of entries.
