Abstract: An asynchronous semiconductor memory device includes an output circuit, which outputs data read from a memory unit, and a high impedance control circuit. The high impedance circuit is connected to the output circuit, stores a burst completion address, and compares a present address with the burst completion address. The high impedance control circuit causes a data output terminal of the output circuit to enter a high impedance state when the present address substantially coincides with the burst completion address. Due to the high impedance control circuit, an exclusive terminal for high impedance control is not necessary.
