ABSTRACT:
In an apparatus for adding first and second addresses to generate a third address and decoding the third address to generate a plurality of partial decoding signals, a plurality of partial decoding signal generating units, each for generating one of the partial decoding signals, are connected in parallel. Each of the partial decoding signal generating units includes an adder for adding a part of the first address to a part of the second address, a carry look ahead circuit, a decoder for decoding the output of the adder, and a shifter for shifting the partial decoding signal of the decoder. A carry output signal of one of the partial decoding signal generating units on the downstream side is supplied to the carry look ahead circuit and the shifter of another of the partial decoding signal generating units on the upstream side.
