Abstract
A semiconductor memory device stably performs a write operation with reduced current consumption. The semiconductor memory device includes a global data, a control unit, a termination resistor unit, and a storage unit. The global data line transmits data. The control unit generates a global control signal during a read operation or a write operation. The termination resistance unit supplies termination resistance to the global data line in response to the global control signal. The storage unit stores the data transmitted to the global data line while the termination resistance unit is inactivated. A method for driving the semiconductor memory device includes detecting a read operation or a write operation and supplying termination resistance when the read or write operation is detected.
