Abstract
A semiconductor device includes a bank group selection signal generation circuit and a bank group address generation circuit. The bank group selection signal generation circuit stores a bank address based on a command pulse generated to perform a read operation or a write operation. The bank group selection signal generation circuit outputs the stored bank address as a bank group selection signal. The bank group address generation circuit generates a bank group address and an internal bank group address for performing a column operation of a cell array included in a bank group selected based on the bank group selection signal.
