Abstract
A semiconductor circuit with the reduced scale of circuitry and a semiconductor integrated circuit chip which is obtained by integrating the semiconductor circuit and enables chip size reduction are provided. For this purpose, a two-decode method is used. The method uses: a pre-decode circuit comprising a first decoder of the preceding stage which decodes an arbitrary bit of an address signal of eight bits and a second decoder of the preceding stage which decodes the remaining bits; level conversion circuits which shift the output of the pre-decode circuit; and post-decode circuits which decode the decode outputs of the decoders in the pre-decode circuit, level-converted through the level conversion circuits.
