Semiconductor memory apparatus, and method for training reference voltage
A semiconductor memory apparatus may be configured to, in a data reference voltage training mode, set a reference pad reference voltage by training a first initial data reference voltage for a reference pad being any one of a plurality of input/output pads, and set a data reference voltage for each of remaining input/output pads by training a second initial data reference voltage being the reference pad reference voltage for each of the remaining input/output pads.
