SEMICONDUCTOR INTEGRATED CIRCUIT, AND SEMICONDUCTOR MEMORY USING THIS CIRCUIT

摘要

PURPOSE: To increase the operation speed of a decoding circuit by making circuit constitution requiring no decoder control signal Π2 out of a control signal Π1 of an address buffer and a control signal Π2. CONSTITUTION: The above mentioned purpose is achieved by uniting an address buffer and a decoder and by providing such a constitution that an output current path of a decoding output is connected in series to a transistor constituting the address buffer and the decoder. When this decoding circuit is used for a semiconductor memory, the access time can be increased, power consumption can be reduced, and the number of cycles can be increased.
