Abstract
A semiconductor system according to an embodiment of the present disclosure includes a controller configured to output a command address, a first chip selection signal, and a second chip selection signal, and a semiconductor device, including a first rank and a second rank, configured to receive the command address, the first chip selection signal, and the second chip selection signal and configured to calibrate each termination resistance value based on the command address, the first chip selection signal, and the second chip selection signal. The first rank calibrates the termination resistance value of the first rank to a target resistance value based on the command address and the first chip selection signal when a write operation on the first rank is performed, and the first rank calibrates the termination resistance value of the first rank to a dynamic resistance value based on the second chip selection signal when a write operation on the second rank is performed.
