Abstract
A semiconductor system includes a process control circuit configured to determine whether to perform a patrol training operation, generate a voltage code signal for adjusting a level of a reference voltage which determines a logic level of data in a target memory circuit, and adjust the voltage code signal on the basis of a fail information signal corresponding to the target memory circuit, an operation control circuit configured to receive a command and an address from a host, generate, from the command, a write signal and a read signal for performing a normal operation, and generate, from the address, an internal address for performing the normal operation and an error detection circuit configured to detect an error in the data by receiving the data from the target memory circuit, and generate the fail information signal depending on whether the error has occurred in the data.
