    Abstract: A semiconductor memory device may include a plurality of data input/output DQ pads and a plurality of first and second memory cell arrays. Each path of a first set of data paths from each of the plurality of first memory cell arrays to a corresponding DQ pad is physically shorter than each path of a second set of data paths from each of the plurality of second memory cell arrays to the corresponding DQ pad. Each of the plurality of first memory cell arrays is a designated first-speed access cell array and each of the plurality of second memory cell arrays is a designated second-speed access cell array, the second-speed being slower than the first-speed. A size of the each of the plurality of first memory cell arrays is smaller than a size of the each of the plurality of second memory cell arrays.

    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.
