ABSTRACT:
A circuit for controlling a driver of a semiconductor memory apparatus includes at least one driving unit in which impedance is set according to a code value, an impedance adjusting unit that outputs a first code and a second code for setting the impedance of the at least one driving unit, a driving reinforcing control unit that outputs an adjustment code for a time corresponding to timing data, and a driving reinforcing unit that outputs a first reinforcing code and a second reinforcing code obtained by adjusting the first code and the second code using the adjustment code, such that a driving capability of the at least one driving unit is reinforced.
