Abstract: A memory system includes a memory device including an interface circuit and a semiconductor memory, and a controller to generate a command for controlling the memory device. The interface circuit receives the command from the controller; determines whether the command is for the semiconductor memory or the interface circuit; and when it is determined that the command is for the interface circuit, performs a blocking operation to block transfer of the command between the interface circuit and the semiconductor memory and performs an internal operation of the interface circuit. The internal operation includes a signal controlling operation, a training operation, a read operation, an on-die termination operation, a ZQ calibration operation, or a driving force control operation.
