Abstract
A method of operating a semiconductor memory device includes setting an operating mode of a mode register to a first operating mode to allow a refresh operation to be performed at intervals of a first period, counting an active command and a pre-charge command by control logic in the first operating mode to generate counting information, comparing a threshold count value with the counting information by the control logic to determine whether the counting information reaches the threshold count value, generating an adaptive mode signal by the control logic when it is determined that the counting information reaches the threshold count value and setting the operating mode of the mode register to a second operating mode in which the refresh operation is performed at intervals of a second period in response to the adaptive mode signal. The second period is less than the first period.
