<p>PURPOSE: To input two kinds of address signals during one cycle time of a clock signal and to output the content of a designated address as a memory output signal in a memory circuit for a semiconductor integrated circuit. CONSTITUTION: A decoder circuit 12 which is constituted of a decoder part 13, a two-input multiplexer 10 and a control signal generation circuit, selects one out of two kinds of address signals which have been input. Then, the decoder circuit 12 decodes a word signal and a select signal. The content of an address which is selected by the word signal and the select signal is latched by a control signal from the decoder circuit 12 so as to be output as a memory output signal.</p> |
