a 256 word by 64 b reconfigurable content addressable memory (rcam) that can be written, searched, or read with a 100 ns cycle time is described. designed for general high-speed table lookup applications, the rcam has self-test and reconfiguration features to simplify testing and improve yield. for more than 256 words, the rcam has extension logic built into the word-finding logic. in a multichip application, all pins of each rcam are tied together, except for the f-line pins (fi, fo, and fd). the f pins ensure that only one chip writes onto the data bus and only one chip stores a word. the fi, fo, and fd are analogous to the carry in, carry propagate, and carry generate signals of a carry look ahead adder
