ABSTRACT:
A semiconductor integrated circuit includes a memory unit that receives data that is to be searched for and matches the data to be searched for with previously stored data; an encoder unit that receives and encodes the memory address of the matched data; and a decoder unit that receives and decodes the encoded memory address and accesses a predetermined word of the memory unit on the basis of the decoded memory address, and the encoder unit and the decoder unit are positioned adjacent to each other on a first side of the memory unit. Consequently, it is possible to connect with a shortened distance the memory address signal lines which are output from the encoder unit and input into the decoder unit to reduce the delay time caused by the wiring, thereby making it possible to improve the operational speed of the circuitry.
