Provided are a dynamic random access memory device having reduced power consumption and a method of determining a refresh cycle of the dynamic random access memory device. The method includes: selecting one or more monitoring bits during first through n-th self refresh cycles, where “n” is a natural number equal to or greater than one; detecting whether the monitoring bits have errors during (n+1)-th through m-th self refresh cycles, where “m” is a natural number equal to or greater than n+1; and adjusting an (m+1)-th self refresh cycle according to whether the monitoring bits have errors.
