Claim 7:
8. The semiconductor system of claim 5, wherein the command generation circuit comprises:
an input command generation circuit configured to generate an input command based on the request signal when the command input signal is enabled and configured to block the input of the request signal for performing the tracking write operation when the flag signal is disabled;
a first command shifting circuit configured to generate a first shifting command by shifting the input command for performing the tracking read operation when the comparison signal and the command end signal are enabled;
a second command shifting circuit configured to generate a second shifting command by shifting the input command for performing an active operation when the comparison signal and the command end signal are enabled and configured to generate the second shifting command by shifting the first shifting command when the comparison signal is disabled and the command end signal is enabled;
a third command shifting circuit configured to generate a third shifting command by shifting the input command for performing the precharge operation when the comparison signal and the command end signal are enabled and configured to generate the third shifting command by shifting the second shifting command when the comparison signal is disabled and the command end signal is enabled;
a fourth command shifting circuit configured to generate a pre-command by shifting the input command for performing the tracking write operation when the comparison signal and the command end signal are enabled and configured to generate the pre-command by shifting the third shifting command when the comparison signal is disabled and the command end signal is enabled; and
a command output circuit configured to generate the command based on the pre-command when the command end signal is enabled.
