Abstract
An address translator has an improved data comparison circuit for comparing two pieces of data having n bits, e.g., 12 bits. In the data comparison circuit, cell circuits compare two pieces of data for every corresponding 4 bits. When a match is detected in the comparison of a set of 4 bits, a signal representative of the comparison result of the lower-order bits is bypassed. Hence, delay of signal propagation which may occur in the cell circuit in which the match is detected is reduced.
