A memory module includes a plurality of integrated memory components are arranged on a mounting substrate and a refresh control circuit arranged separately from the memory components on the mounting substrate. The output of the refresh control circuit is connected to the plurality of integrated memory components. The refresh control circuit receives and processes address or command signals which have been generated outside the memory module; based on the access information obtained therefrom, independently generates a refresh command or a refresh command sequence for refreshing the contents of memory cells in a selected one of the memory components; and transmits the command or command sequence to the selected memory component. Refresh commands of this type no longer have to be generated by a memory controller.
