Provided are a memory device and a method of refreshing the memory device regardless of a refresh rate multiplier for a temperature. In response to a refresh command at each base refresh rate (tREFi) based on a measured temperature, a memory device refreshes M memory cell rows at room temperature, refreshes 2M memory cell rows at a high temperature, and refreshes (&#xbd;)M memory cell rows at a low temperature. The memory device refreshes (n+1)*M memory cell rows at a base refresh rate tREFi in response to a refresh command applied after n skipped base refresh rates, and refreshes (n+1)*M memory cell rows at a base refresh rate tREFi in response to a pulling-in refresh command.
