Abstract: PURPOSE: A control device for a mode register setup is provided to improve the stability of a circuit by preventing fail operation generated due to unnecessary activation of a mode register setting signal in the time of a disable of a command buffer. CONSTITUTION: A control device for a mode register setup includes a differential amplifier having an n type current mirror structure in order to generate an output signal having a voltage level complementary to a mode register setting order signal in disable time. At this time, because an enable control signal(ckeb_com) in a low signal state is applied, a command buffer is enabled, and the final output data signal(Vout) becomes a low signal state on the occasion of an input data signal(Vin) in a high signal state. On the contrary, on the occasion of the input data signal(Vin) in a low signal state, the final output data signal(Vout) becomes a high signal, and has a phase opposite to a phase in the time of the disable of the command buffer. For this reason, in the time of the disable of the command buffer, it is prevented that a mode register order signal is set up into a fail operation.
