ABSTRACT:
A page access circuit of a semiconductor memory device is normally operated even when a page address toggles at any timing in a page mode. The page access circuit comprises an address buffer, a column control unit, a page control unit, a pre-active unit and a precharge unit. The column control unit is controlled by the page address control signal. The page control unit controlled by a sense detecting signal is adapted and configured to generate the page address control signal. The pre-active unit controlled by the page address control signal is adapted and configured to generate a mode identification signal in response to the page address transition detecting signal. The precharge unit is adapted and configured to perform a selective precharge operation in response to the mode identification signal.
