Abstract:
A column address control circuit comprises a control unit for outputting a control signal in response to a DDR mode signal and a first signal, and an address counting unit configured to receive a start column address and output a start column address in response to the control signal. The first signal is a burst read single write mode signal. The control signal is activated when the first signal is activated in a DDR mode. The control unit includes a first logic unit for performing an AND operation of the DDR mode signal and the first signal, and a second logic unit for performing an OR operation of an output signal of the first logic unit and a SDR mode signal.
