Abstract:
A circuit for setting a reference voltage is provided. The circuit includes a reference voltage information storage unit and a reference voltage input/output (I/O) control unit. The reference voltage information storage unit is configured to set a level of a reference voltage according to information stored in a first register or a second register if a training operation starts in a first set mode. The reference voltage I/O control unit is configured to set a level of the reference voltage according to first data or second data if the training operation starts in a second set mode.
