ABSTRACT:
A buffer circuit of a semiconductor memory apparatus includes a buffering section configured to increase or decrease a voltage level of an output node by comparing a voltage level of an input signal with a voltage level of a reference voltage. A voltage compensation section applies a voltage to the output node in proportion to a variation of the reference voltage when the level of the reference voltage is lower than a target level.
