摘要:
A semiconductor memory device includes a mode register, an additional function executer, and an additional function controller. The mode register activates an additional function control signal when a mode register set code indicates that an additional function is to be executed concurrently with a refresh operation. The additional function controller controls the additional function executer to carry out the additional function concurrently with the refresh operation when the additional function control signal is activated.
