Abstract
A semiconductor apparatus may include a column select signal generation circuit and a control signal generation circuit. The column select signal generation circuit may generate a column select signal by driving an output node of the column select signal with a first drivability in response to a column decoding signal and adjust the first drivability according to a drivability control signal. The control signal generation circuit may generate the drivability control signal according to a row decoding signal.
