Abstract
A semiconductor memory device for performing highspeed address access and highspeed data access is provided by controlling a control/address block in synchronization with a delay locked loop (DLL) clock. The semiconductor memory device includes a clock buffer for buffering an external clock; a delay locked loop (DLL) for generating a DLL clock in synchronization with the external clock; a control signal buffer for receiving and buffering an external control signal to generate an internal control signal in synchronization with the DLL clock; and an address buffer for receiving and buffering an external address signal to generate an internal address signal in synchronization with the DLL clock.
