US Patent 7447109 Semiconductor storage device

Disclosed is a semiconductor storage device which has a shared address/data terminal that shares an address terminal and a data terminal. In a latency period extending from receipt of an access command to a cell array to input or output of data, which corresponds to an access command, from the shared address/data terminal, pipeline control is performed in response to receipt of at least one other access command. Input or output of data from the shared address/data terminal corresponding to the other access commands is performed successively following data that corresponds to the initial access command.
