Abstract: In one example embodiment, a memory system includes a memory module and a memory controller. The memory module is configured generate density information of the memory module based on a number of the bad pages of the memory module, the bad pages being pages that have a fault. The memory controller is configured to map a continuous physical address to a dynamic random access memory (dram) address of the memory module based on the density information received from the memory module.
