ABSTRACT:
A semiconductor memory device comprises a driver including a first resistor, and a control signal generator including a second resistor. A storage unit is employed to store adjustment data for setting a resistance of said second resistor at a designed resistance, which is specified based on the state of the control signal actually obtained when the resistance of the second resistor is set to a certain designed value. The storage unit is referred to for stored data to switch the second resistor to control the state of the control signal. In addition, the first resistor is switched to a resistance corresponding to the resistance of the second resistor.
